## Summary
- Removes the `plaintext-transactions` Pennant feature flag — plaintext
is now the default for all users
- Removes encryption guards and `isPlaintext` conditionals from
transaction create/edit/import flows, keeping only the plaintext code
paths
- Makes `EncryptionKeyButton` conditional — only shown when user has
legacy encrypted accounts or transactions
- Removes encryption onboarding steps (`step-encryption-explained`,
`step-encryption-setup`) and related state/props
- Updates landing page to replace E2E encryption marketing with
privacy-first messaging ("Your Data, Your Rules" section)
- Updates privacy policy to replace E2E encryption claims with accurate
security language (encryption at rest, TLS in transit, no third-party
sharing)
- Cleans up tests to remove feature flag assertions and
`Feature::activate()` calls

## Test plan
- [x] Create a transaction without encryption key unlocked — should
succeed
- [x] EncryptionKeyButton should not appear in header for users with no
encrypted data
- [x] EncryptionKeyButton should appear for users with legacy encrypted
transactions/accounts
- [x] Landing page has no E2E encryption references, shows new privacy
section
- [x] Onboarding flow has no encryption setup steps
- [x] Privacy policy reflects accurate security language
- [x] Frontend builds successfully (`bun run build`)
- [x] All linting passes (`bun run lint`, `vendor/bin/pint --dirty`)
