feat: update application versioning and enhance release management

- Bumped application version to 1.0.0 across all relevant package files, ensuring consistency in versioning.
- Introduced new environment variables for application version and release URL in Dockerfiles, improving deployment transparency.
- Enhanced the health check endpoint to return the current application version, providing better visibility for monitoring.
- Updated CI/CD workflows to include steps for preparing and publishing releases, streamlining the release process.
- Added a new "Releases" section in the application sidebar for easier access to version information.
