Fix: Legendary camouflage parts, materials, names and attachments

Fixes a batch of legendary camouflage problems in the Tankopedia viewer, adds three missing unique camouflages and lets attachments be shown together with a camouflage.

## Camouflage parts (state switchers)
- Camouflages now choose which tank pieces show the same way the game does. Each switcher's load-time scenario script runs at export time (checks for attached camouflage items, or compares the camouflage preset), along with its state-switch actions. This replaces the old guess from part names (new `core/blitzkit/switcherStates.ts`).
- Fixes missing roof MGs, fenders and fuel tanks (IS-3 Bear, Obj. 140 Terror, IS-7, IS-4, FV215b 183, AMX 50 B, KV-1S) and default parts mixed into camouflages (Pershing Speedfire, Forest Witch Fullmetal, Waffenträger Goldstreifen).
- Switchers inside camouflage parts now show one state instead of all of them stacked (Obj. Kust double net, Goldstreifen stowage, Tiger II cat).
- States are matched by original node names, because the GLTF loader renames duplicates.
- Camouflage part meshes with no LODs (`lodIndex -1`) are kept, which restores the Tiger II cat body and missing pieces on about 11 other camouflages.

## Materials
- `AlphaBlend` materials export as transparent. `AlphaBlendAdditive` materials export as additive and are applied in `jsxTree`, and unlit `Textured` materials export as unlit (IS-8 Raroh flames, dinosaur holograms, and glass and screens on a few base tanks).
- Camouflage part materials that share a name with the tank's material no longer replace the tank's camouflage material (Bisonte C45 Unbreakable).

## Names
- With a legendary camouflage selected, the title shows the tank's in-battle name ("GuP Type 95 Ha-Go", "KV-1 Warrior", "Shinobi").
- Camouflages without a name in the game files yet show "Unreleased" in orange instead of their raw string key, and no longer crash the tank names list.

## Attachments
- Attachments (`kind: customization`) are listed in their own group under the camouflages and can be turned on together with a camouflage. They load the same way as camouflages and fade with the same transition.

## Other
- Liberté, You Rock! and Ozzie (single-tank camouflages that only set a preset through `override`) are now available.
- Mastery gun mark meshes (`custom_gun_marks_*`) are no longer drawn (Helsing, HWT20 FalconFire and two camouflage guns).

## Not included
- Pixel Wave, Digital Trace and Forest Shadow are tiled pattern camouflages, which the viewer can't render yet.
- FV301 Corbie's drone position and the dinosaur heads' glow depend on camouflage animations and emissive materials, which are separate PRs.
