Standard query panels previously required custom renderers or application wrappers for common extensions. This change lets consumers customize the built-in panels while retaining their interaction behavior and existing defaults.

• Support typed attachment models throughout QueryEditor and QueryPage, local file selection with retry, and configurable validation. Applications retain ownership of file I/O and persistence.
• Add descriptions, indicators, inline actions and menus to standard navigation rows, plus an additional header menu trigger. Update virtualized row heights when descriptions change.
• Add per-attribute editing permissions and draft validation to QuerySettings, and allow standard fields to be hidden without losing their values.
• Extend FieldsSelector with search, explicit Apply/Cancel, a selected count and custom trigger content, forwarding options through consuming panels.
• Document the new contracts and add stories, component tests, type fixtures and browser coverage.

Validation on a7562c1:

• npm run test:components — 732 tests passed.
• npm run test:types — passed.
• npx playwright test tests/browser/standardPanels.spec.ts — 4 tests passed.

Checks used UIKit 7.45.1; the minimum supported peer version was not separately tested.
