fix(uninstall): prompt before restoring pre-OMZ zshrc backup

Browse source 
Silently restoring .zshrc.pre-oh-my-zsh during uninstall could overwrite
years of user config with a stale backup from install time, with no
warning or recovery path. Fixes #13156, fixes #13328.

Changes:
- Clarify the timestamped backup message so users know it holds their
  current config, not a throwaway file
- Show the modification date of the pre-OMZ backup before restoring it
- Prompt for confirmation before restoring; default is N (no restore)
- If user declines, print both file paths so they can merge manually
- Cross-platform date: tries macOS `date -r` then GNU `stat -c %Y`
