[Merge After #102][PATH] Add debug endpoints to PATH chart

[adshmh]

Summary

Add debug endpoints routing with API key authentication and refactor health check configuration

Primary Changes:

• Add debug_endpoints authentication configuration with dedicated API key secret for secure debug access
• Create path-pprof service to expose pprof endpoints on port 6060 for internal cluster access
• Enable debug endpoints routing through guard with separate authentication from main API

Secondary Changes:

• Refactor health check configuration structure in values.yaml with clearer defaults and documentation
• Bump chart versions: path from 0.1.26 to 0.1.27, guard dependency from 0.1.24 to 0.1.32
• Add TODO comment for future API key security improvements using K8s secrets

@okdas Can you pick up this PR and push it over the finish line?

Direction (not code) is a 👍 from my end EVEN if it doesn't work on prod for now.

Same as #102 - looks good, but would appreciate additional functionality behind the values flag.

1. Resolve conflicts and merge this in
2. end to the comment from @okdas regarding switches here in a followup commit?
