feat: MK5 shading; fix redundant MK3 trim

[UXLZ]

MK5 Complex + Backpack
Redundant trim removed (MK3 given MK4 trim, it gained one variant, maybe it's not a lore accurate one idk but they were otherwise the same.)

Tested visually.

---

Summary by cubic

Adds shaded MK5 Complex armour and backpack sprites and wires them into the modular renderer for better depth and lighting. Also cleans up trim selection and moves MK5 setup to culture visuals.

• New Features

  • Added spr_mk5_complex_shadow and spr_mk5_complex_backpack_shadow and hooked them into scr_culture_visuals for “MK5 Heresy”.
  • Updated MK5 Complex and backpack base sprites.

• Refactors

  • MK5 Heresy armour/backpack now selected via scr_culture_visuals instead of scr_ComplexSet.
  • MK3 now uses MK4 right trim with shadows and flip in scr_culture_visuals; redundant MK3 trim removed.

^{Written for commit e38e2b7. Summary will update on new commits.}

scripts/scr_culture_visuals/scr_culture_visuals.gml	2052	armours: ["MK5 heresy"] — lowercase 'h' typo causes the backpack shadow sprite to never render for MK5 Heresy units; array_contains is case-sensitive in GML

---

🏆 Best part: The sprite plumbing work (shadows, struct structure, muscling armours out of scr_ComplexSet.gml into culture visuals) is genuinely well done — the architecture here is clean.

💀 Worst part: The "MK5 heresy" typo at line 2052 means the MK5 Heresy backpack sprite was technically added AND will never display. That is the software equivalent of buying a gift and throwing it in a woodchipper before giving it. The shadow asset files exist, the registry entry exists, but the name check silently rejects them at runtime.

📊 Overall: Like a race car with no fuel line — the engine's there, the parts are there, but it's going nowhere fast.
