fix(P1+P2): swarm review — UX fixes + V1 dead code cleanup

P1 — UX visible:
- Add 4 missing translations (leather_mittens, ball_gag_3d, taser, debug_wand)
- Fix earplugs resistance bucket: "blindfold" → "earplug"
- Split mixin config: core (require=1) + compat MCA (require=0)
- Bump PROTOCOL_VERSION from "1" to "2"
- Add debug_wand item model (no texture — debug only)
- Fix 3 display_name inconsistencies (chain, vine_seed, shock_collar_auto)

P2 — Dead code cleanup:
- Delete IHas3DModelConfig + Model3DConfig (zero imports)
- Remove MovementStyleResolver.resolveV1Fallback() + V1Fallback record + V1 constants
- Remove AnimationTickHandler V1 fallback block + buildAnimationId()
- Document PlayerEquipment.equipInRegion() bypass as intentional (force-equip paths)
