fix(documents): skeleton loading, calmer review badge, larger touch targets

The inbound-document list and review panels used centered spinners; swap
them for the app's Skeleton pattern so the resolved content lands without
a layout jump. The low-confidence review badge moves from destructive red
to a calm amber, matching the surface's non-alarming posture. Approve /
reject / edit / save controls grow to the 44px touch floor, the upload
file input gains an accessible label, and each document row exposes
aria-expanded.
