Feat/ranged combat and loadout

[Shaileshukla529]

Summary

Fixes map branding and enemy sizing on the LG wall, and updates the setup docs for port 8111 and Edge TTS.

Changes

• Decals: map logos render at 0.8× their Tiled box (GSoC 0.88×, NEAREST filtering) instead of filling it; both logo PNGs re-exported larger.
• Enemies: dragon scale 1.4 → 0.78, mimic gets bodyHeight: 34, and render.bodyHeight is threaded through to the client entity config.
• README: setup rewritten as ordered steps (nvm Node 16 → clone + symlink → verify → controller app), :3000 → :8111 throughout.
• ISSUES.md: dropped the VirtualBox routing section; firewall is now a footnote since 8111 is whitelisted.
• CREDITS.md: per-pack usage and modification notes, plus the missing PvP wall tiles.
