feat(launcher): reorganize cfg drawer into Setup/Hardware/Dev tabs

- Setup (default): Oral/Poster preset, WS Controller, Screen Saver
- Hardware: Electron health/OS/updates (native only) + Sync control
- Dev: Local reset/debug tools — tab hidden until Edit Mode is on

Edit Mode toggle added as subtle pencil icon in the cfg drawer header
(low opacity when off, primary-colored when active). This is intentional
— onsite kiosk operators should not stumble on it, but admins doing
setup can find and toggle it without leaving the drawer.

Dev tab visibility and the Debug Panel button both gate on edit_mode,
keeping the default view clean for non-technical operators.
