Pull request overview

This PR adds manifest upload capabilities for server packages (historian, gitrest, routerlicious) and introduces a --useCurrentVersion flag to the build-cli release report command. The changes enable prerelease and release manifest generation for server packages with exact version mappings, and allow the release reporting tool to use unreleased in-repo versions when tag history doesn't yet contain them.

Changes:

• Created shared template include-upload-release-reports.yml to avoid code duplication in manifest upload steps
• Added upload-server-manifest.yml with support for both prerelease and release manifest generation
• Extended flub release report command with --useCurrentVersion flag for using unreleased in-repo versions
