Add option for Playtest 1 rules

New side hit location tables and ammo explosion cap.

[Copilot]

Pull Request Overview

This PR implements Playtest Package #1 Survivability Rules, introducing new side hit location tables and less lethal ammo explosions to improve unit survivability in BattleTech gameplay.

Key changes include:

• New side hit location logic for all Mek types that uses front-facing hit tables and maps results to appropriate side locations
• Ammo explosion damage cap system (20 damage normally, 10 with CASE) that blows out armor when exceeded
• New game option to enable/disable these playtest rules

Please replace the multiple identical code blocks with a function, and move the option check out of applyPlaytestExplosionReduction() and up into the calling function.
