Add release version and commit links to footer with GitHub releases

[Mbd06b]

This commit implements the following enhancements:

1. Footer Display Changes:

   • Added release version link (e.g., v1.0.0) pointing to GitHub releases page
   • Kept existing commit hash link for easy access to specific commits
   • Both links now visible in the footer build info section

2. Environment Configuration:

   • Added version field to all environment files (prod, staging, alpha, dev)
   • VERSION_PLACEHOLDER added for build-time replacement in prod/staging/alpha
   • Local dev environment uses '1.0.0-dev' for development

3. Jenkins Pipeline Updates:

   • Updated Build App stage to replace VERSION_PLACEHOLDER with BASE_VERSION
   • Added new "Create GitHub Release" stage for main branch deployments
   • Release creation includes:
     • Checks if release already exists to prevent duplicates
     • Creates annotated git tag (e.g., v1.0.0) * Pushes tag to GitHub * Creates GitHub release via API with deployment metadata
   • Requires 'github-pat' credential in Jenkins

4. Component & Test Updates:

   • Updated FooterComponent to include version and githubReleaseUrl
   • Added comprehensive tests for version link rendering
   • Updated existing tests to verify both release and commit links

This enables users to easily navigate to both the specific release version and individual commits from the application footer.
