feat: add file path selection and fix save bug

- Add file path selector before starting (default to Desktop)
- Display current save file path in UI
- Remove 'Save Current' button (auto-save to selected file)
- Fix: All vanity addresses now save to the same user-selected file
- All chains (TRON/EVM/SOL) save to same file with chain label
