fix(matrix-stats-bot): adapt to Umami v2 API response format

The Umami API returns stats in a different format than expected:
- Before: { pageviews: { value, change } }
- After: { pageviews: number, comparison: { pageviews: number } }

Transform the raw API response to the expected format and calculate
percentage change from comparison values.

Also update URL_SCHEMA.md with complete list of all mana.how services.
