CobbleGacha Expanded Alpha 3.7.16

Gacha animation polish:
- Keeps the 3.7.15 portal/summoning animation.
- Hides the legacy "Arceus's Wishes" counter and "Spinning..." text while the charge animation is playing.
- Makes ULTRA pulls substantially more cinematic:
  * longer 3.4 second flash sequence
  * denser charge particles
  * converging divine rays before the flash
  * multiple expanding gold/cyan/magenta rings
  * 40 rotating rarity/star spokes
  * three-stage white/gold/cyan flashes
  * large celestial cross burst
  * animated double border around the summon area
  * orbiting divine sparks
  * late shockwave sequence
  * 52-particle reveal burst
  * lingering corner starbursts, halo rings, and gold rain during reveal
- Regular pull animation remains the same style with only the text cleanup.
