feat: add scripted presentation registries

[vdmkenny]

Changes

• Add mod-qualified camera views, HUD displays and selected UI screens with shared context cleanup, failed-load rollback and protected callbacks. Camera views respect mission locks and validate poses and object lifetimes.
• Add all twelve built-in interface groups beneath ordinary mod overrides, reusing existing API declarations for bindings and generated references.
• Add the Strafe Run example combining an order, HUD display, chase camera, help panel and rebindable actions.

Screens provide overlays and input callbacks through the existing drawing API; original controls still receive keys. Campaign progression and menu-flow APIs remain covered by #442 and #560.

Validation

• 1,922 tests passed, one skipped, including registry lifecycle, callback failure, mod isolation, override restoration and the complete example.
• ReleaseSafe build, generated definitions, formatting, file checks and diff checks passed.
• 44 original missions checked with no problems; 45 installed missions bound with no failures.

Closes #558
