fix: sync Helm chart versioning with production standards and Docker versions (#18868)

* fix: sync Helm chart versioning with production standards and Docker versions

- Update Chart.yaml version from 0.4.10 to 1.0.0 (SemVer 0.x is for development, 1.0+ for production)
- Update appVersion from v1.50.2 to v1.80.12 to match current Docker image version
- Update workflow defaults from 0.1.0 to 1.0.0 for new chart version scheme
- Maintain independent chart versioning per Helm best practices

This ensures:
- Helm chart follows SemVer production standards (1.x instead of 0.x)
- appVersion stays synchronized with Docker/application version
- Chart version remains independent for flexibility (can update chart without waiting for app releases)

* fix: sync Helm chart appVersion with Docker image tags in release workflow

Updates the GitHub workflow to ensure Helm chart appVersion matches the
Docker image tags that are actually published:

- For stable/rc releases: Uses the workflow input tag (e.g., v1.80.12)
- For latest/dev releases: Uses the release_type to match main-{type} tags
- Makes 'tag' input required to prevent accidental releases with wrong versions
- Simplifies fallback logic by removing git-describe dependency

This ensures the chart's appVersion correctly references Docker images
that exist, preventing deployment failures from missing image tags.

* Update ghcr_deploy.yml
