Cobblemon Battle Tower

- Added Wild Battle API as a required dependency on both Fabric and NeoForge.
- Added boss-only effectively infinite PP so boss encounters no longer run out of moves.
- Added dedicated boss music for Rayquaza boss
- Added stronger phase-transition particles and tuned per-boss screen shake.
- Added custom boss aura particles with curated per-boss color themes for G-Max and special boss encounters.
- Fixed two-phase boss encounters so phase transitions now reset battle state cleanly and avoid leftover gimmick or stat-stage carryover.
- Fixed Mega Rayquaza phase 2 persistence and transition behavior, and fixed the Fabric startup crash caused by the boss-aura mixin remap configuration.
- Fixed Battle Tower run stats so floors with itemusage = 0 now display 0 instead of None.
