fix: update Antigravity model list and replace ag/ prefix with antigravity/

- Replace stale model IDs (gemini-3.1-pro-preview, gemini-3.1-flash-lite-preview)
  with correct High/Low tier variants from fetchAvailableModels API
  (gemini-3-pro-high, gemini-3-pro-low, gemini-3.1-pro-high, gemini-3.1-pro-low, etc.)
- Remove ag/ alias prefix in favor of antigravity/ across registry, providers,
  model capabilities, combos, docs, and static model providers
- Make provider alias optional in Zod schema and guard ALIAS_TO_ID/ID_TO_ALIAS maps
- Show raw model IDs in quota display instead of unmapped display names
- Update T28 model catalog test to assert new High/Low tier models
