- Options page gains a 'Default tablet for this machine' picker,
populated from the device list once base URL + terminal key are
configured, auto-saved on change (small enough setting not to warrant
its own Save button).
- Popup pre-selects the default in its device dropdown but still shows
the full picker — opening the popup is already a deliberate action, so
staff can still override it there.
- Injected buttons (row + banner) skip the dropdown entirely when a
default is configured — one click pushes straight to it. Only falls
back to the full picker if that specific push comes back busy (409),
with a note explaining why it's asking despite a default being set.
background.js's pushBooking() now returns the HTTP status alongside
ok/error so this can be detected reliably rather than string-matching
the error message.
