feat: revamp web hub — global connection status, array config editor, log streaming

- Global connection badge in app header (persistent dashboard SSE via ConnectionProvider)
- LogProvider keeps log data and SSE stream alive across page switches (no reload spinner)
- Config drawer: password reveal toggle, array-type row editor for list fields
- Plugin management: optimistic updates, race-free loading, reset all group overrides
- Logs: load-earlier pagination; backend tail-read optimization (before/end offsets)
- web_auth: Web password changes persist (sync_admin seeding only when .env has explicit key)
- Dashboard: collect in thread pool + 1s result cache
- ErrorBoundary + local Suspense: plugin chunk loading stays inside content area
- UI polish: table row hover, mobile header/breadcrumb fixes, wider config drawer
- config_standard: array type inference for list fields; array env skip
- random_jm_code / steam_info: array schema migration; README web frontend note
