* Add support for extra secrets and config maps in helm deployment template
* expose single env field in values field instead of extra secret and config map fields
* a small fix

This PR adds DNS configuration support to the LibreChat Helm chart, enabling users to redirect traffic to proxy servers or use custom DNS settings.
## What's Changed
- Added dnsPolicy and dnsConfig fields to deployment.yaml template
- Added DNS configuration options to values.yaml with comprehensive examples
- Created documentation and example configurations
## Use Cases
- Redirect AI service traffic (AWS Bedrock, OpenAI, etc.) to proxy servers
- Use corporate DNS servers for name resolution
- Control traffic routing through custom DNS configurations
- Enforce traffic through security gateways
## Configuration Example
```yaml
dnsPolicy: "None"
dnsConfig:
nameservers:
- "10.0.0.10" # Custom DNS server for redirections
searches:
- "svc.cluster.local"
options:
- name: ndots
value: "2"
```
## Testing Results
✅ Successfully tested with Docker Compose environment
✅ DNS resolution correctly redirects to configured IPs
✅ HTTP requests properly routed to proxy servers
✅ Tested with multiple domains (AWS Bedrock, OpenAI, SageMaker)
Test output:
- bedrock-runtime.us-east-1.amazonaws.com -> 172.25.0.10 ✓
- api.openai.com -> 172.25.0.10 ✓
- sagemaker-runtime.us-east-1.amazonaws.com -> 172.25.0.10 ✓
All DNS redirects working correctly with proxy server receiving traffic.
## Documentation
- Added comprehensive DNS_CONFIGURATION.md guide
- Included examples for common use cases
- Provided troubleshooting steps
## Backward Compatibility
This change is fully backward compatible. If dnsPolicy and dnsConfig are not specified, the default Kubernetes DNS behavior is maintained.

- Update MongoDB chart dependency from v16.3.0 to v16.5.45
- Add explicit containerPort configuration with fallback to service.port
- Standardize port references in health probes to use explicit port numbers
- Add targetPort and containerPort fields to service configuration
- Include service type options as inline comment for better clarity
These changes improve the Helm chart's port management flexibility and
bring the MongoDB dependency up to date with the latest stable version.
