Frontend: dynamic status pipeline, categories/projects, tag+assign+reallocate UI

- Board/List/Today views now render the admin-editable status pipeline
  instead of a hardcoded todo/doing/done enum (StatusesContext)
- Category filter chip-bar on Board and List views (ported the idea from
  reviewing the FD's own build, simplified to match our flat single-category
  model rather than his tree)
- New Projects list + detail views, project create/edit modal
- New Dispatch view for the 'reallocate' cap -- flat cross-user task list
  with an inline move action (deliberately not routed through the shared
  task drawer, since GET /api/tasks/:id only grants visibility to
  owner/assignee/tagged users, not dispatchers)
- Task drawer: dynamic status pills, category/project selects, tag
  picker (share/watch, no cap needed), assign field (owner + assign cap),
  reallocate field (reallocate cap) -- all fields disabled for non-owners
  since the backend's single PATCH endpoint is owner-gated
- Settings page: status pipeline + category management (settings cap)
- Fixed missing input[type="datetime-local"]/[type="time"] styling -- the
  Due/Remind fields were rendering with unstyled browser defaults
