CobbleGacha Expanded Alpha 3.7.34

Publication/banner cleanup pass:
- Keeps the full English reward-card rarity labels: COMMON / RARE / EPIC / ULTRA / LEGENDARY.
- Replaces the four low-quality scribble-style default banners (Standard, Arcane Clash,
  Starter, Dragon) with the newly generated smooth cosmic/energy-wave art.
- Replaces the visually repetitive circle-and-line template family with distinct smooth
  wave/energy variants while preserving each banner's original texture path.
- Improves Tempest Incarnate, Treasures of Ruin, Island Guardians, Roar of Johto,
  Wings of Kanto, Stars Beyond, Eon Duality, Genetic Origins, Origin of All,
  Primal Tempest and Truth & Ideals so the default gallery no longer looks duplicated.
- Adds a dedicated super_duper.png instead of reusing truth_ideals.png.
- Existing user configs containing the old Super Duper duplicate texture mapping are
  upgraded non-destructively on load.
- Fresh installs still use the supplied configured banner definitions as the built-in defaults.
- CobbleGacha config files remain grouped under config/cobblegacha/ with automatic legacy migration.
- No pull probabilities, rewards, IV rules, animation logic, or gameplay classes changed.
