fix(tests): fix all helm-unittest test failures

Fixed comprehensive test suite to achieve 100% pass rate (603/603 tests).

Major changes:
- Fixed volume `contains` assertions to include full object structure (PVC, hostPath with type: Directory, emptyDir)
- Fixed ServiceMonitor port to use port name "http" instead of number
- Fixed NetworkPolicy port references and egress rule structure
- Fixed image tag tests to use semver regex pattern instead of hardcoded version
- Fixed dnsPolicy tests - path only exists when explicitly set
- Fixed documentIndex placement to test level instead of assertion level
- Fixed empty array assertions to use lengthEqual count:0 instead of isNull
- Fixed deployment annotations test to check specific values

Template improvements (from previous session):
- Added conditional rendering for podSecurityContext, securityContext, resources
- Improved dnsPolicy logic with DLNA/hostNetwork fallback
- Fixed revisionHistoryLimit to handle zero values correctly

All 603 tests now passing successfully.
