feat: fix tooltip shortcuts and add dev server config dialog

Tooltip fixes (PR #177 follow-up):
- Remove duplicate title attr on Settings button that caused double-tooltip
- Restore keyboard shortcut hints in tooltip text: Settings (,), Reset (R)
- Clean up spurious peer markers in package-lock.json

Dev server config dialog:
- Add DevServerConfigDialog component for custom dev commands
- Open config dialog automatically when start fails with "no dev command"
- Add useDevServerConfig/useUpdateDevServerConfig hooks
- Add updateDevServerConfig API function
- Add config gear button next to dev server start
