The saved-signature browse/delete/place controls gave too little feedback, so
users re-clicked them repeatedly (the icon-only Use/Remove buttons were the
top rage-click target on /sign, alongside Pause/Resume placement).
- Remove is async (a network round-trip for backend storage) but showed no
loading state and stayed enabled, so repeated clicks fired several delete
requests and, once one resolved, the next signature slid into the same card
slot — looking like nothing happened. It now shows a spinner and disables the
category controls while the delete is in flight.
- Use is an icon-only control with no confirmation; it now shows a transient
"Selected" success state so the click clearly registers.
- The saved-signature carousel now wraps around so it is quicker to cycle.
- Pause/Resume placement gained descriptive tooltips and clearer paused-state
copy explaining what the mode does and how to resume (button or Esc).
- Signing is applied client-side (endpoint: null), so completions never reached
the shared execute path that emits editor_operation. Emit it on a successful
apply so abandonment on this flow is measurable.
