Add ROM upload, local table library, engine bump, and UX/responsiveness fixes

- Bump @valknar/vpinball-wasm to 0.3.2 (PinMAME ROM support, MsgBox fix)
- Add optional PinMAME ROM .zip upload alongside .vpx tables
- Persist uploaded tables/ROMs in IndexedDB so users don't have to
  re-upload on later visits, with a library list on the landing page
- Fix Insert Coin key mismatch with the engine's real coin-door gating
  (now bound to 4, matching the shared table scripts) and surface it
  in the controls legend and "Tap to Start" hint
- Make the landing page, staging panel, and in-game HUD responsive for
  portrait phone widths; drop the landscape hint since portrait plays fine
- Replace the separate STATS HUD toggle with an FPS row in the info panel
