feat(hooks): WS RPC surface + tenant-scope guards + shared test runner

Exposes agent hooks over WebSocket (hooks.list/create/update/delete/ toggle/test/history) behind existing auth layer. Additions: - Gateway wiring: buildHookHandlers() factory reused by dispatcher and hooks.test runner, so UI test panel exercises production code paths - GetByID tenant-scope guard: non-master callers only see own tenant + global rows (matches List() behavior on both PG and SQLite) - i18n keys + catalogs (en/vi/zh) for hooks error messages - Protocol method constants for hooks.* and config.defaults
