- Add OAuth1 to OAuth2 token exchange using Garmin's exchange endpoint
- Track refresh token expiry (~30 days) instead of access token expiry (~21 hours)
- Auto-refresh access tokens in cron sync before they expire
- Update Python script to output refresh_token_expires_at
- Add garminRefreshTokenExpiresAt field to User type and database schema
- Fix token input UX: show when warning active, not just when disconnected
- Add Cache-Control headers to /api/user and /api/garmin/status to prevent stale data
- Add oauth-1.0a package for OAuth1 signature generation
The system now automatically refreshes OAuth2 tokens using the stored OAuth1 token,
so users only need to re-run the Python auth script every ~30 days (when refresh
token expires) instead of every ~21 hours (when access token expires).
