feat(flutter): send timezone on login + app-start + weekly

Flutter client posts FlutterTimezone.getLocalTimezone() to
PUT /api/me/timezone on every setSession (login / register success)
and on every AuthController.build (app cold-start with valid
session), when the locally-stored tz_last_sent_at is >7 days old.
Cadence tracked in flutter_secure_storage so it survives app
restarts.

Failures swallowed: the server's UTC default + last-known value
keep the scheduler functioning until the next attempt.

Completes the client side of #392 Half B (per-user timezone
scheduling).
