feat: Add Claude Sonnet 4.5 tracking to CloudWatch dashboard (#37)

- Add Sonnet 4.5 detection to log query with pattern matching that distinguishes 4.5 from 4.0
- Update token_by_model widget to display Sonnet 4.5 separately with purple color
- Add comprehensive throttle tracking across 7 global regions (US, EU, APAC)
- Track global.anthropic.claude-sonnet-4-5-20250929-v1:0 model ID

This ensures Sonnet 4.5 is tracked as a distinct model with its unique capabilities,
separate from Sonnet 4, across all dashboard widgets and metrics.
