feat(admin): inline quick-adjust stepper for account priority

Replace the static priority number in the accounts table with a compact
stepper: hover reveals -/+ buttons, clicking the value allows typing
(Enter to save, Esc to cancel, arrow keys to nudge). Rapid clicks are
debounced into a single priority-only PUT, failures revert the value and
surface a toast, and the row is patched in place without a full reload.
