feat: implement versioning and release management in the project

- Added automatic versioning based on git tags using semantic-release in Gitea Actions.
- Introduced new API endpoints `GET /version` and `GET /v1/version` to expose build metadata.
- Updated Docker build process to include version and build time information in Go binaries.
- Enhanced documentation with details on release processes and versioning guidelines.
- Integrated version display in the web application for better user visibility.
