Update Gitea workflow to include frontend build step and adjust Go build command

- Added a step to install and build the frontend using npm in the test-pr.yaml workflow.
- Modified the Go build command to compile all packages instead of specifying the output binary location.
- This change improves the build process by integrating frontend assets with the backend build.
