Add optional GPG signing status display in commits pane

Add a new gui.showGpgSigningStatus config option that, when enabled, shows GPG signature verification status for each commit in the commits view. Uses git's %G? format placeholder to display colored indicators: green check for valid signatures, red X for bad/revoked, yellow tilde for missing keys, and blue dash for unsigned commits.

Disabled by default since GPG verification adds latency to commit loading.

Closes #5363
