Increase rate limits on polling endpoints

Fix 429 errors caused by aggressive rate limiting on now-playing APIs.
Changed from 2-3 req/sec to 60 req/min for:
- asteroid/partial/now-playing
- asteroid/partial/now-playing-inline
- asteroid/partial/now-playing-json
- asteroid/channel-name

This fixes notifications not working and may resolve auto-reconnect issues.
