Refactor weapon visual data declarations to reduce duplication

[coderabbitai]

Description

The weapon visual data declarations in scripts/scr_culture_visuals/scr_culture_visuals.gml contain repetitive boilerplate code. Each weapon entry repeats the same base.weapon_data structure with display_type and new_weapon_draw: true.

Location

• File: scripts/scr_culture_visuals/scr_culture_visuals.gml
• Approximate lines: 1256-1352 (and potentially other weapon declarations)

Impact

• Increases maintenance friction when patterns change
• Violates DRY principle
• Creates unnecessary code duplication

Context

This issue was identified during code review of PR #878 where new 30k weapons were added, highlighting the repetitive pattern.
