Boot fix for Iridescent Ball visual assets.
- Reverted to the Cobblemon-compatible geometry from 1.0.41 because the uploaded geo.json used per-face UV objects that Cobblemon's loader rejected.
- Kept the ball/particle/beam locators.
- Replaced invalid animation particle effect IDs with valid Cobblemon effect identifiers.
- Fixes unrecognized particle effect cobblemon:ballsparkle during animation loading.
