Inventory polish: smaller phone/notebook, phone higher, auto-open, exit to board

The phone and notebook render a bit smaller; the phone sits higher on screen;
in-game the handset opens automatically (session mode); and the tool view
gains an EXIT ✕ that closes the inventory straight back to the board.
