Merge feat/knowledge-base: KnowledgeBase UI

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) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

hzhang	14ac03b551	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) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-05-31 15:03:50 +01:00
hzhang	04bb0c6f94	feat(role-editor): "Use as template" — copy another role's perm set Adds a select+button next to the permission editor: pick any other role from the dropdown, click "Use as template" → all checkboxes are replaced with that role's permission set. Local-only (no API call); the user still hits "Save changes" to persist. Includes a banner confirming the load with the source role name + perm count. Selector excludes the currently-edited role. Hidden for non-admins. UI: dark card row matching the Foundry Deck token system (--bg-card, --text-dim mono label, --bg-sink select with --accent focus border).

hzhang	766474f4e9	style(role-editor): rewrite UI on Foundry Deck dark tokens Replace hardcoded light-theme inline colors (#fff/#f8f9fa/#e8f5e9/#888…) with semantic CSS classes that consume the existing design tokens (--bg-card/--ember/--ember-soft/--accent/--text-dim/--steel/etc.). Fixes the unreadable role names, faded checkmark cards, and washed-out success banner — everything was rendering "white-on-cream" against the dark Foundry Deck background. Visual structure now: - two-column grid (sidebar 280px / detail flex) - role-card: dark surface, ember-soft + 3px ember edge + glow on selected, Saira Condensed display name + mono permission count - perm-group card with dashed steel header - perm-item: bg-sink default; ember-soft + accent border + ember-tint check glyph on checked; native checkbox restyled with the ember palette - banner pill: success-green or danger-red token, mono text - create-role card: ember left-edge, mono uppercase labels - delete uses .btn-danger (already in the token set) No state/logic changes — same fetch + toggle + save flow.

hzhang	f587e1e4c7	fix(frontend): drop localStorage HF_BACKEND_BASE_URL; env-only api.ts + useAuthConfig kept the old wizard-era localStorage path for the backend URL, which is why fresh browsers saw blank pages on MonitorPage and any other api-using page after the v0.4.0 wizard removal — without the wizard pre-seeding localStorage, getApiBase() returned undefined and axios called same-origin (frontend nginx, 404). App.tsx getApiBase() partially worked because I had only refactored that one path; api.ts (used by everything else) still had its own duplicate getApiBase that I missed. This commit removes the localStorage path entirely from all 3 read sites (api.ts / App.tsx / useAuthConfig.ts) — single source of truth is now the build-time env baked in by the Dockerfile ARG. - src/services/api.ts: const API_BASE = import.meta.env.VITE_HF_BACKEND_BASE_URL - src/App.tsx: const API_BASE = ... (replaces getApiBase()) - src/hooks/useAuthConfig.ts: const BACKEND_BASE = ... - src/test/setup.ts: stub import.meta.env instead of localStorage key Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-24 19:17:05 +01:00
