feat(knowledge-base): Knowledge Base UI — browse/edit, modal, project links

- Knowledge Bases list page + sidebar entry + "+ New" create modal
- Detail page with a recursive structure tree: add/edit/delete topics,
  categories and facts inline, including name + description editing
- Create/metadata-edit modal (title, description)
- Project edit modal gains a link/remove knowledge base section
- Types and routes for /knowledge-bases and /knowledge-bases/:id
- Scoped .kb-* styles (contained panel, topic cards, hierarchy guides)

 # HarborForge.Frontend
 
-HarborForge Frontend - React + TypeScript
+Single-page web client for HarborForge — the agent/human collaborative
+task-management platform. It provides the operator UI for projects,
+milestones, tasks, proposals, calendar/meetings, users, roles and the
+live monitor, and walks operators through first-time provisioning via the
+SSH-tunnel Setup Wizard.
+
+Part of the [HarborForge](../README.md) platform.
+
+## Tech Stack
+
+- **React 18** (`react`, `react-dom`)
+- **TypeScript 5**
+- **Vite 5** dev server / bundler (`@vitejs/plugin-react`)
+- **react-router-dom 6** for client-side routing
+- **axios** for HTTP, with a shared request/response interceptor layer
+- **dayjs** for date handling
+- **Vitest 4** + Testing Library (`@testing-library/react`, `jsdom`) for unit tests
+
+Path alias `@` → `src/` (configured in `vite.config.ts` and `tsconfig.json`).
+
+## Pages
+
+Routes are declared in `src/App.tsx`. The app gates rendering on three
+states — `checking` (probing configuration), `setup` (Setup Wizard), and
+`ready` (authenticated app). `/monitor`, `/login`, `/roles` and `/users`
+are reachable without an authenticated session; everything else requires login.
+
+| Route | Page | Purpose |
+|---|---|---|
+| `/` | `DashboardPage` | Landing dashboard |
+| `/tasks` | `TasksPage` | Task list / filtering |
+| `/tasks/:taskCode` | `TaskDetailPage` | Task detail, transitions, comments |
+| `/projects` | `ProjectsPage` | Project list |
+| `/projects/:id` | `ProjectDetailPage` | Project detail / editor |
+| `/milestones` | `MilestonesPage` | Milestone list |
+| `/milestones/:milestoneCode` | `MilestoneDetailPage` | Milestone detail / actions |
+| `/proposals` (`/proposes`) | `ProposalsPage` | Proposal list |
+| `/proposals/:proposalCode` (`/proposes/:proposalCode`) | `ProposalDetailPage` | Proposal detail, accept/reject/reopen |
+| `/calendar` | `CalendarPage` | Calendar view |
+| `/meetings/:meetingCode` | `MeetingDetailPage` | Meeting detail |
+| `/supports/:supportCode` | `SupportDetailPage` | Support request detail |
+| `/notifications` | `NotificationsPage` | Notification inbox |
+| `/roles` | `RoleEditorPage` | Role / permission (RBAC) editor |
+| `/users` | `UsersPage` | User management |
+| `/monitor` | `MonitorPage` | Live system monitor (public) |
+| `/login` | `LoginPage` | Authentication |
+| _(state-gated)_ | `SetupWizardPage` | First-run provisioning wizard |
+
+Shared building blocks live in `src/components/` (`Sidebar`,
+`CreateTaskModal`, `MilestoneFormModal`, `ProjectFormModal`,
+`CopyableCode`); the auth hook is `src/hooks/useAuth.ts`; shared types are
+in `src/types/index.ts`.
+
+## How It Talks to the Backend
+
+All API access goes through the shared axios instance in
+`src/services/api.ts`:
+
+- The base URL is **resolved at runtime** from
+  `localStorage['HF_BACKEND_BASE_URL']` (re-read on every request via an
+  axios request interceptor), not baked in at build time.
+- A bearer token from `localStorage['token']` is attached automatically
+  when present.
+- A response interceptor clears the token and redirects to `/login` on
+  HTTP `401`, except on the public paths `/monitor` and `/login`.
+
+Authentication (`src/hooks/useAuth.ts`) posts form-encoded credentials to
+`/auth/token`, stores the returned `access_token`, and loads the current
+user from `/auth/me`.
+
+In local dev, `vite.config.ts` also proxies `/api/*` to
+`http://backend:8000` (stripping the `/api` prefix) for same-origin
+development against a Compose backend.
+
+## Setup Wizard / SSH-Tunnel Flow
+
+On startup `App.tsx` runs `checkInitialized()`:
+
+1. It calls the backend `GET /config/status`. If that returns
+   `initialized: true`, the app is `ready` (and `backend_url`, if present,
+   is cached into `localStorage['HF_BACKEND_BASE_URL']`).
+2. Otherwise, if a wizard port was previously saved
+   (`localStorage['HF_WIZARD_PORT']`), it tries
+   `http://127.0.0.1:<port>/api/v1/config/harborforge.json` directly.
+3. If neither indicates an initialized install, it renders
+   `SetupWizardPage`.
+
+The Setup Wizard (`src/pages/SetupWizardPage.tsx`) is a 4-step flow —
+**Wizard → Admin → Backend → Finish**:
+
+- **Wizard**: the operator enters the local port that an SSH tunnel
+  forwards to **AbstractWizard**
+  (`ssh -L <port>:127.0.0.1:<port> user@server`). The UI health-checks
+  `http://127.0.0.1:<port>/health` and stores the port.
+- **Admin**: collects the first admin account (username, password, email,
+  full name).
+- **Backend**: optional backend base URL override.
+- **Finish**: writes the assembled config to AbstractWizard via
+  `PUT http://127.0.0.1:<port>/api/v1/config/harborforge.json`, caches the
+  backend URL locally, and instructs the operator to
+  `docker compose restart` on the server before refreshing.
+
+## Local Development
+
+```bash
+npm install
+npm run dev          # Vite dev server on http://0.0.0.0:3000
+```
+
+The dev server proxies `/api` to `http://backend:8000` and allows the
+hosts `frontend`, `127.0.0.1`, `localhost`.
+
+### Build
+
+```bash
+npm run build        # tsc type-check, then vite build → dist/
+npm run preview      # serve the production build locally
+```
+
+### Test
+
+```bash
+npm test             # vitest run (jsdom)
+npm run test:watch   # watch mode
+npm run test:ui      # Vitest UI
+```
+
+Tests live in `src/test/**/*.test.{ts,tsx}` (e.g. `calendar.test.tsx`,
+`proposal-essential.test.tsx`) with global setup in `src/test/setup.ts`.
+
+### Docker
+
+```bash
+docker build -t harborforge-frontend .
+docker run -p 3000:3000 harborforge-frontend
+```
+
+The multi-stage `Dockerfile` builds with Node 20 and serves `dist/` via
+`serve` on port 3000. Set `FRONTEND_DEV_MODE=1` to run the Vite dev server
+inside the container instead of serving the static build.
+
+## Environment / Configuration
+
+- **`VITE_API_BASE`** (`.env`, default `http://backend:8000`) — a build
+  hint for the default backend location.
+- The effective backend base URL is determined at **runtime** from
+  `localStorage['HF_BACKEND_BASE_URL']`, which is populated by the Setup
+  Wizard or by the backend's `/config/status` response — so changing the
+  backend target does not require a rebuild.
+- `localStorage['HF_WIZARD_PORT']` — last AbstractWizard tunnel port.
+- `localStorage['token']` — current JWT bearer token.
+
+## Theming
+
+The entire visual design is a single self-contained design system in
+**`src/index.css`** — there is no CSS-in-JS, no Tailwind, and no
+per-component stylesheets. Components only reference global CSS classes;
+all colors, typography, spacing and effects are driven by CSS custom
+properties on `:root`. To re-theme the app, edit this one file.
+
+The theme is **"Foundry Deck"** — a shipwright's drafting table meets a
+foundry control panel:
+
+- **Blackened-steel dark palette** — cool-tinted near-black surfaces
+  (`--bg`, `--bg-card`, `--bg-hover`, `--bg-sink`) with machined,
+  tight-radius borders.
+- **Molten-ember accent** — a single hot orange accent
+  (`--accent`, `--accent-hover`, `--ember` gradient, ember glow) used
+  sparingly as the signature element.
+- **Oxidized-steel secondary** plus a forge-mapped status palette
+  (patina success, heat-amber warning, rust danger, arc violet).
+- **Blueprint-grid background** — layered radial ember/steel vignettes, a
+  fine 40px draughting grid, and a subtle SVG film-grain overlay.
+- **Technical web fonts** loaded via a Google Fonts `@import` at the top
+  of `src/index.css`: **Saira Condensed** (headings), **Hanken Grotesk**
+  (body), and **JetBrains Mono** (code/monospace).
+
+Selectors are kept 1:1 with the existing markup, so theming changes are
+made entirely in `src/index.css` via the CSS variables and global classes.
