shaw 9d3cc4507f fix(antigravity): keep legacy default passthroughs and bill Claude 5.5 tier IDs at base rates
- Restore runtime default passthroughs and Gemini 3.1 Pro aliases for
  explicit Antigravity model_mapping. Mappings saved before the Gemini
  3.x Flash / 3.1 Pro releases still depend on them; dropping them would
  silently remove those models from existing accounts on upgrade.
- Capability sync now skips injected-only passthrough targets, so models
  the upstream catalog omits no longer mark the sync as partial.
- Price Antigravity claude-{opus,sonnet}-5-5-{high,medium,low} at the base
  Opus/Sonnet 5.5 card instead of substring-matching claude-opus-5 /
  claude-sonnet-4-5 (1.25x-3x overbilling).
