install.sh: add existing OEMDRV reuse, git origin conflict handling, refined permissions

- Detect existing OEMDRV partition at startup; offer to reuse it
  instead of creating a new one (mounts if needed, sources existing
  setup_system.inc.sh before cloning)
- When existing repo origin/branch differs from REPO_URL/REPO_BRANCH,
  offer to pull from existing origin, migrate to new origin (preserving
  gitignored local files), or fall through to fresh clone
- Extract finish_install() and do_clone_and_done() helpers to share
  clone, permissions, and configure.sh prompt across all paths
- Replace generic chmod with chown root:root + chmod ug=rwX,o=rX
  recursively, plus o+w on config/ and config.d/
