Rename Tracked Events to Tracked Items, add More>> spillover, lock recap cadence

- Tracked items get the same isSpillover flag as categories: a per-item "More"
  checkbox collapses it into the "More »" nav tab instead of its own top-level
  tab, mirroring Category.isSpillover end to end (schema, CRUD, public API,
  nav partitioning, /more page).
- Renamed user-facing "Tracked events" text to "Tracked items" (admin tab,
  toolbar, buttons, placeholders, /event/:id subtitle) — the underlying
  TrackedEvent/events data model and routes are unchanged.
- Locked the per-item recap cadence dropdown (previously a live
  Continuous/Daily/Hourly picker) and moved it to its own labeled section with
  an explanatory hint: reading eventsRecap.ts confirmed Continuous and Hourly
  currently behave identically, so the live choice was more confusing than
  useful. New items are fixed to Continuous; existing items show their real
  cadence read-only.
