Subject: [PATCH 1/2] test(web): cover Ctrl+Insert as a terminal copy shortcut

Shift+Insert already pastes. Ctrl+Insert currently falls through because
isTerminalCopyShortcut only matches the C key.

Subject: [PATCH 2/2] fix(web): copy terminal selection with Ctrl+Insert

Mirror the Shift+Insert paste branch. Ctrl+Insert is the GTK/VTE copy
chord and the one tiling WMs send for universal clipboard on a terminal
window. Copy only, do not treat it as SIGINT.

Closes #8525
