Cobblemon: Extended Battle UI

Bug Fixes

• Damage Numbers: Fixed damage percentages being wildly inaccurate after Pokemon switch in (e.g., showing "+43%" for 6% poison damage). HP baselines are now captured at switch-in time for accurate calculations.
• Pokeball Indicators (Servers): Fixed player team pokeballs always showing full health on multiplayer servers. Now correctly reflects KOs, status conditions, and HP changes during battle.
• Pokeball Side Alignment: Fixed pokeball indicators sometimes appearing under the wrong player's tiles. Indicators now properly align with Cobblemon's battle UI positioning.
