CobbleGacha Expanded v1.7.0 Alpha 3.7.5

Pokemon Settings stability rebuild based directly on Alpha 3.7.0.
- BannerEditor rendering is short-circuited while Pokemon Settings or a picker is open; the underlying builder is not rendered at all.
- Removes Pokemon/icon bleed at the source rather than covering it with a modal rectangle.
- Restores -10 / -1 / +1 / +10 for shiny chance, level and every custom IV.
- Searchable Held Item, Nature and Ability pickers.
- Nature defaults to RANDOM; Ability defaults to DEFAULT.
- Per-stat RND toggle for custom IVs; random IVs persist through save/reload.
- Wider three-column layout with reserved right padding for the +10 IV controls.
- Dedicated left live form preview; normal-size fallback is always drawn and a larger isolated render is attempted last.
- Form/region changes invalidate the ability cache and update the preview source.
- Ability picker prioritizes legal form abilities then attempts to enumerate the full Cobblemon ability registry.
- SET button remains available on every Pokemon row.
