fix(ui): align logs row and detail panel via shared accessors

Both surfaces now consume `getDisplayModule / getDisplayStage /
getDisplayRequestId / getDisplayLatency` from `utils.ts`, replacing the
previous divergence where the list row fell back to `source` while the
detail panel showed em-dash placeholders for the same entry.

Also widens the request-id column in the row table from 88px to 112px
and adds a hover-revealed clipboard icon for one-click copy of the full
requestId. List header bumped to 12px sans-serif uppercase + 9h height
for legibility.
