fix(build): replace upload-artifact@v4 with direct Gitea API upload

upload-artifact@v4 uses a backend API incompatible with Gitea (GHES).
Collapse to a single job that builds both targets sequentially and uploads
directly to a Gitea release via the REST API, removing the need for
artifact passing between jobs entirely.
