Plaid ClientId/Secret are now stored per-user in the database
(encrypted) instead of in appsettings.json. Users enter their own
Plaid developer credentials in the Settings > Bank Connections tab.
- New BankSyncSettings model (1:1 with User) for encrypted credentials
- PlaidSyncProvider is now stateless, receives credentials per-call
- Settings UI shows a credentials card with save form
- Connect via Plaid button disabled until credentials are configured
- Removed Plaid section from appsettings.json
