fix(codex): patch all users, not just root — add --all flag and fix macOS UID threshold

- Install script now runs patcher with --all to patch every user's ~/.codex/config.toml
- Fix list_users() UID threshold: macOS starts at 500, Linux at 1000
- Fix file ownership: chown config files to the actual user after patching
