fix(ui): show version+SHA+build time in footer; fix env not reaching runtime image

PUBLIC_BUILD_VERSION and PUBLIC_BUILD_COMMIT were set only in the builder
stage ENV — they were never re-declared in the runtime stage, so the Node
server started with them undefined and the badge always showed 'dev'.

Fix: re-declare all three ARGs after the second FROM and set runtime ENVs.
Add PUBLIC_BUILD_TIME (ISO timestamp from gitea.event.head_commit.timestamp)
injected via build-arg in release.yaml. Badge now shows e.g.:
