feat(ops): /api/version endpoint with git SHA + build time

Adds a public, no-auth endpoint at /api/version that returns:
  { commit, commitShort, buildTime, nodeEnv, cutover, nextVersion }

Build-time injection via GIT_COMMIT + BUILD_TIME ARG/ENV propagated
from compose build.args through Dockerfile builder + runner stages.
Excluded from middleware auth gating.

Deploy command (run on satra after git pull):
  GIT_COMMIT=$(git rev-parse HEAD) \
    BUILD_TIME=$(date -u +%FT%TZ) \
    docker compose build architools

Without these env vars, falls back to "unknown" so the build never
fails; only the endpoint shows reduced info.

Useful for: confirming what's actually deployed after CI, cross-app
deploy correlation (api.gis.ac, eterra.live, orchestrator), uptime
monitors.
