Subject: [PATCH] Configure git credential.helper=store system-wide

Prevents git from trying to open /dev/tty for password prompts in
environments without a controlling terminal (live ISO, scripts, Claude Code).
Credentials stored once in ~/.git-credentials and reused automatically.

Applied to: both live ISO include overlays and the installer target system.
