fix: Increase rate limit for localhost/Docker testing

Fixes HTTP 429 errors during test suite execution by allowing 10,000 requests per 15 minutes for localhost and Docker network IPs, while maintaining 100 requests for external IPs.

Changes:
- Rate limit: 10,000 for localhost/Docker (127.0.0.1, ::1, ::ffff:172.x.x.x)
- Rate limit: 100 for external IPs (security maintained)
- Fix make_calendar tool to properly construct calendar URLs
