Same move as the watches, and the config's last piece of integration
state goes with it:
- `rhema-calendar-integration` owns the calendar table now
(`store.rs`): SQLite in the shared dispatch database, the pattern
the claw's watch table established. `CalendarWatch` gains the
`validate` the config's boot check used to run — per-kind URL and
credential rules, plus the lead-under-horizon check — so an invalid
calendar is loud at the one door every writer shares.
- `CalendarSource::from_store` reads the table fresh on every detect
pass (the forge source's pattern): a calendar added over the route
is live next tick, a removed one stops polling, no restart in the
story. The static constructor stays for tests.
- `POST/DELETE/GET /v1/calendars` on the daemon: the POST body is the
integration's `CalendarWatch` shape, validated at the table; DELETE
takes `?name=`; the api listing names the door.
- `ClawConfig.calendars` is gone. A config still carrying it is
refused at parse time, like the retired `watches:` seed. The
config-side validation and its tests moved with the type.
The config file now carries only what boot needs: credentials, the
surface, paths, the poll cadence. Everything the daemon reconfigures
at runtime lives in its tables, behind its HTTP doors.
