CobbleGacha Expanded Alpha 3.7.21

Single-pull reveal card pass:
- Replaces the tiny reveal strip with a larger card-style result reveal.
- Adds a dedicated showcase window in the middle of the card.
- Shows the pulled Pokemon/result name prominently.
- Adds an IV footer under the card.
- IV line is parsed heuristically from the reveal description if present.
- Adds animated glow / orbit / showcase effects to make the result feel like a card instead of plain text.

Important note:
- This is the UI/card system pass. The current client payload still only exposes the result description string directly to this screen.
- So the card uses the result text and parsed IV text. It does NOT yet instantiate a full Cobblemon 3D model entity in the reveal panel.
- Multi-pull reveal list remains unchanged in this pass.
