fix(ci): replace release-action with direct Gitea API calls

The gitea.com/actions/release-action is archived and requires go to
build from source, which isn't available in the ubuntu-latest runner.
Replace with curl calls to the Gitea release API: create release,
upload assets. Handles existing releases by deleting and recreating.
