Add a viewer option to ignore fullbright globally: render every face as if its fullbright flag were off, so it's lit by sun, moon, local lights and probes like any other surface. Fullbright surfaces otherwise glow at night, wash out photos, and ignore the environment.

Behaviour:

New setting, e.g. SlipstreamIgnoreFullbright (default off), with a checkbox in Preferences > Graphics (and maybe Photo Studio).
When on, treat the fullbright bit as 0 for every legacy (Blinn-Phong) face.
- Decide whether PBR emissive stays as authored, since emissive isn't fullbright; probably yes, possibly with a separate option.
- Glow stays as authored unless a follow-up wants a separate toggle.
Applies to world objects, attachments and avatars. HUDs are excluded: HUD fullbright is UI and stays.
Takes effect live with no relog. Ideally it's a shader-side override (a frame-info flag checked where the fullbright bit is read) rather than re-ingesting faces.
Check the cases that rely on fullbright: invisiprims and alpha tricks; media faces, where fullbright media should probably stay readable (consider exempting media faces); particles, which aren't a face flag (out of scope unless trivial).

Where:

the clean pipeline's fullbright handling in indra/vkclean/shaders (lightSurface / the fullbright branch in clean_draw / clean_surface_light);
how the fullbright bit reaches the GPU (instance or material flags in llvovolume ingest);
deferred G-buffer flags.

Done when: toggling the option turns every fullbright surface into a normally lit one immediately and back again, with HUDs unaffected.

Done: b407e8fd68 (SLIgnoreFullbright: Preferences > Advanced > Ignore fullbright) and 67e32ca5ce (the toggle now applies immediately instead of on the next object update). Verified by the owner. Lands in 1.2.0 Beta 8.
