all: remove saved views, the Has-reminder filter and the Created range

Step 18 of the audit follow-through (#5180), on the operator's decisions.
Inkwell is for capture and recall (note 2897), and these three duplicated a
surface that does the job already:

- Saved views. They lived only on the web; the desktop kept its own set that
  never synced, and Android had none. Tags in the drawer already give
  one-click recall. Gone from the server (routes, model, migration 0038 drops
  the table), the core (store functions, schema v13 drops its table), the
  desktop commands, the web adapters, the drawer's Views list and the
  "Save view" link.
- The "Has reminder" facet. The Reminders page lists them, sorted by due.
- The FilterBar's "Created" range. Timeline is the date lens and keeps the
  created_after/created_before query it builds from local days, which also
  retires the UTC/local-day disagreement between the two (B3).

An old link that still carries the removed keys opens the plain board; a
web test pins that.
