Increase negentropy sync limit from 100k to 1M events (v0.55.5)

- Add MaxEvents config option to negentropy manager
- Increase default sync limit from 100,000 to 1,000,000 events
- Ensures full database sync for relays with 200k+ events

Files modified:
- pkg/sync/negentropy/manager.go: Add MaxEvents config, use configurable limit
- pkg/sync/negentropy/server/service.go: Increase hardcoded limit to 1M
