- encryptionService.js: getKey() tries TOKEN_ENCRYPTION_KEY env first, then
auto-generates a random 48-byte key on first startup, persists to settings
as _auto_encryption_key. assertEncryptionReady() is now a no-op.
- bankSyncConfigService.js: removed encryption_key_set response and
encryptionKeyReady() helper. No env config required.
- .env.example: TOKEN_ENCRYPTION_KEY removed. Comment says enable from Admin
panel, no env config required.
- BankSyncSection.jsx: added SimpleFIN Bridge links — 'Open SimpleFIN Bridge'
for first-time setup, 'Get a SimpleFIN token' for existing connections
- Removed disable logic and key warning banner from BankSyncAdminCard
- Toggle works freely regardless of TOKEN_ENCRYPTION_KEY status
- encryptionKeyReady and encryption_key_set left as informational only
