Merge branch 'worktree-check-security-audit'

Security and frontend-correctness hardening: analytics IDOR fix, scraper
log scrubbing, lowercase email normalisation (migration 009), stale-response
guards in the plan hooks, busy flags cleared unconditionally across all
useLatestRequest consumers, Calendar no longer blanks on mutation, plus
dependabot/CI config and removal of the stray frontend/out.js.

Conflicts came from main's later "day assertions" restructure, which made
usePlannedDays read-only and replaced the calendar's per-day add/update with
useDayAssertions.assertDay. Both intents kept:

- usePlannedDays: branch's fetch machinery (isRefreshing, in-flight dedup,
  unguarded busy clear); mutators dropped as on main.
- usePlanSync: branch's useLatestRequest guard also applied to main's new
  syncWithWish.
- useDayAssertions / useLatestBalance (new on main): busy flag now cleared
  unconditionally, as the branch did for every other consumer.
- useDayAssertions.assertDay gains the branch's `skipRefresh` option and a
  `refresh`, so Calendar's multi-day save keeps the batch shape (N writes,
  one trailing bumpPlanVersion + one assertions refresh) on main's
  assertDay path. Branch's M7 tests ported from the removed add/update API
  to assertDay.
- PlanSyncProvider: branch's isAuthenticated gate kept; eviction-preview
  state stays removed as on main.
- usePlannedDayExclusions.ts stays deleted (superseded by useDayAssertions).
