Wire the existing TUI autocompleteMaxVisible plumbing into the
declarative settings system so it appears in /settings under the
Input tab. Users can pick from 3/5/7/10/15/20 items; the TUI editor
clamps to 3-20 regardless.
- Add autocompleteMaxVisible to SETTINGS_SCHEMA (number, default 5)
- Add OPTION_PROVIDERS entry for the submenu dropdown
- Handle runtime side-effect in selector-controller
- Set initial value from settings on editor construction
- Add tests for default, runtime, persistence, and config loading
