feat(scheduler): persist recurring daily starts

Add a local-calendar daily start scheduler with pending receipts, per-day deduplication, DST-safe target calculation, missed-day recovery, and retryable account/start failure outcomes.

Persist and validate the daily rule, expose its next target to the renderer, preserve legacy one-time schedules until a daily rule is saved, and gate boot auto-resume on recorded active-run evidence.

Wire boot, settings, account, suspend, resume, interval, and shutdown lifecycle handling with focused RED/GREEN coverage for calendar, persistence, renderer, and controller boundaries.
