fix(ui): show a human-friendly version in the auth footer

The footer rendered raw `git describe` output (e.g. "v0.1.0-beta.1-7-ge49ba2e")
on any build past a tag — the -<commits>-g<sha> tail looks broken to users.
Add formatVersion() to collapse it to "<tag> (<sha>)", so the footer reads
"v0.1.0-beta.1 (e49ba2e)". Settings keeps the full precise string for support.
