feat: safety plan version history with diff view

- Each save pushes current plan to versioned history (max 20)
- History modal shows versions with timestamps
- Diff view highlights additions/deletions between versions
- One-click restore to any previous version
- Only saves versions when content actually changes

Fixes #96
