Fix GPT-5 API compatibility and add AIUsageLog migration

- Add AIUsageLog table migration for token tracking
- Fix GPT-5 temperature parameter (not supported, like o-series)
- Add usesNewTokenParam() and supportsTemperature() functions
- Add GPT-5+ category to model selection UI
- Update model sorting to show GPT-5+ first

GPT-5 and newer models use max_completion_tokens and don't support
custom temperature values, similar to reasoning models.
