feat: add API config system, FilePipe backend, and ConfigManager

- ConfigManager: route sensitive keys (API keys) to localStorage,
  migrate existing values out of extension_settings on startup
- ApiKeyStore: local/cloud storage modes with RSA+AES hybrid encryption
- ApiProfileManager: named connection profiles (chat/embedding/rerank)
  with per-slot type-validated assignments
- FilePipe: complete IndexedDB backend (read/write/delete/list/stat)
- Amily2Bus: inject FilePipe via forPlugin() capability token
- UI: api-config-panel with profile CRUD and slot assignment
- TableSystemService: initial service layer scaffold
- logger.js: XSS fix
