feat(atlas): per-job CI status + build-injected version in the UI

Phase C: the CI stage now shows the latest run's per-JOB status (Lint/Test,
Build, Deploy, …), each coloured by outcome, from the Gitea /actions/tasks
per-job entries — replacing the static cd.yml job-id list when live.
LatestRunJobs/RunNodes + RunSummary.State aggregate, all test-first.

Version: injected at build via -ldflags from `git describe --tags` (CI checkout
now fetch-depth:0 + --build-arg), served in /api/atlas.json, shown in the header.
No more hand-maintained version label drifting from the git tag.

Verified: build/vet/lint(0)/test green; version ldflag served correctly.
