test(httproute): add comprehensive unit tests and deployment notes

Add helm-unittest test suite for HTTPRoute (Gateway API) covering:
- Not created by default (enabled: false)
- Created when enabled with required configuration
- Annotations support
- parentRefs configuration (name, namespace, sectionName)
- Hostnames support (single and multiple)
- Path matching rules (PathPrefix, Exact)
- Multiple rules and multiple matches per rule
- Backend references to Jellyfin service
- Custom service port handling

Add NOTES.txt with HTTPRoute-specific deployment information:
- Gateway references and configuration status
- Configured hostnames
- Number of routes
- Backend service details
- Access URLs when hostnames configured
- Warnings for missing parentRefs

Tests ensure HTTPRoute works correctly across all Gateway API scenarios.
