## Summary
- Store account names in plaintext instead of encrypting them
client-side. Encryption remains only for transaction descriptions and
notes.
- Existing encrypted account names are silently migrated when the user
unlocks their encryption key, via a new `useDecryptAccountNames` hook
that calls API endpoints to update each account.
- New `AccountName` component handles rendering both encrypted (legacy)
and plaintext accounts across the app.
## Test plan
- [x] Create a new account — name should be stored in plaintext
(`encrypted = false`, `name_iv = null`)
- [x] Unlock encryption key with existing encrypted accounts — they
should auto-migrate silently
- [x] After migration, verify accounts show `encrypted = false` in DB
and names are readable plaintext
- [x] Edit a migrated account — should work without encryption
- [x] Verify all account name displays work across dashboard, account
details, transactions, settings
