Add email warnings for Garmin token expiration at 14-day and 7-day thresholds.
When the garmin-sync cron job runs, it now checks each user's token expiry and
sends a warning email at exactly 14 days and 7 days before expiration.
Changes:
- Add sendTokenExpirationWarning() to email.ts with differentiated subject
lines and urgency levels for 14-day vs 7-day warnings
- Integrate warning logic into garmin-sync cron route using daysUntilExpiry()
- Track warnings sent in sync response with new warningsSent counter
- Add 20 new tests (10 for email function, 10 for sync integration)
Test count: 517 → 537

Added three Garmin API endpoints for token management:
- POST /api/garmin/tokens: Accepts oauth1, oauth2, expires_at;
encrypts tokens using AES-256-GCM; stores in user record;
returns daysUntilExpiry
- DELETE /api/garmin/tokens: Clears encrypted tokens from user
record and sets garminConnected to false
- GET /api/garmin/status: Returns connection status, days until
expiry, expired flag, and warning level (critical ≤7 days,
warning 8-14 days)
All endpoints use withAuth() middleware for authentication.
Added 26 tests covering encryption, validation, auth, and
warning level thresholds.
Also added pb_data/ to .gitignore for PocketBase data.

Add the core daily snapshot API that powers the dashboard. Returns:
- Training decision (status, reason, icon) using decision engine
- Cycle data (cycleDay, phase, phaseConfig, daysUntilNextPhase)

Add authentication infrastructure for protected routes:
- withAuth() wrapper for API route handlers (src/lib/auth-middleware.ts)
- Next.js middleware for page protection (src/middleware.ts)
withAuth() loads auth from cookies, validates session, and passes
user context to handlers. Returns 401 for unauthenticated requests.
Page middleware redirects unauthenticated users to /login, while
allowing public routes (/login), API routes (handled separately),
and static assets through.
Tests: 18 new tests (6 for withAuth, 12 for page middleware)
Total test count: 60 tests passing
