refactor(scribe): remove calendar + entity surfaces from web UI (frontend)

Frontend half of the narrowing (milestone #194); matches backend b49efdc.

- delete CalendarView, EventSlideOver, WeatherCard (orphan)
- drop /calendar route + nav link + the g→l keyboard shortcut
- strip the calendar-events API client + event/metadata bits from note
  types and the notes store
- KnowledgeView: remove People/Places/Lists tabs, entity cards, create
  buttons and the upcoming-events widget; keep notes/tasks/plans/processes
  + the overdue-task badge
- NoteEditorView: remove person/place/list forms + list-builder + entity
  metadata; keep note + process editors (type select = Note/Process)
- DashboardView: drop the "Upcoming · 7 days" events rail card
- SettingsView: remove the CalDAV integration card + save/test (its
  endpoints were deleted backend-side)
- prune the now-dead entity/event CSS

RecurrenceEditor + task recurrence rules are kept (task machinery, not
calendar). Verified by a full dangler sweep.
