Load File: finalize first-click deterministic apply, add NoReturn, and align docs

- Stabilize Load File first-click behavior across mission/map/options/slots.

- Fix map sequencing by rebuilding game-type scenario list before mission lookup.

- Resolve mission-name miss to map index 0 fallback for selected game type.

- Fix decal handling: map INI decal IDs to dropdown indices, clamp invalid indices, display actual decal IDs in UI labels, and avoid redraw-time decal overwrite.

- Fix option apply timing and UI visibility issues, including Weapon Jam refresh.

- Add NoReturn support end-to-end: parse/store in MW4Shell auto globals, expose script variable, and apply to respawn/no-return mission params and UI checkbox.

- Update autoconfig spec to reflect actual parser/default/fallback behavior and add NoReturn examples.
