feat: switch cli indexing to code-first identifiers

- Add hf calendar command group to command surface and router
- Implement schedule/show/edit/cancel/date-list commands
- Implement plan-schedule/plan-list/plan-edit/plan-cancel commands
- Add leaf help for all calendar commands
- Align CLI with backend calendar routes and response envelopes
- Support virtual slot ids for edit/cancel
- Validate with go build and go test ./...
