- Change SESSION_PREFIX from 'session@' to 'manage@session@' to prevent
sessions from appearing in file index and backups
- Add KV expirationTtl for automatic session cleanup on expiry
- Fix D1 adapter: route all manage@ keys to settings table instead of
files table (fixes blockipList and session storage in wrong table)
- Fix D1 list({ prefix: 'manage@' }) not matching settings table
(fixes backup not containing settings data)
- Exclude manage@session@ keys from settings backup export
