Summary

Fixes #19 - When one Polar API endpoint returns an error (e.g., 403 on sleep due to missing data sharing consents), the sync now continues with other endpoints instead of failing entirely.

Changes

• SyncResult dataclass - New return type that tracks both successful record counts and per-endpoint errors
• Per-endpoint error handling - Each _sync_* call is wrapped in try/except so failures don't stop other syncs
• Actionable error messages - 403 errors now include guidance: "Check consent settings at https://account.polar.com or re-authenticate with Polar"
• Partial success UI - New sync_partial.html template shows both synced data and errors in a yellow warning banner
• SyncOrchestrator updates - Properly tracks partial success status in SyncLog

Before

If sleep endpoint returned 403, entire sync failed - no data synced at all.

After

If sleep returns 403:

• Error captured with actionable message
• Other endpoints (recharge, activity, exercises, etc.) continue syncing
• UI shows partial success with details on what failed and why

Test plan

• Unit tests added for new behavior (tests/test_sync_error_handling.py)
• All 77 existing tests pass
• Type checking passes (mypy)
• Linting passes (ruff)
• Manual test with real 403 error (need account with limited scopes)
