fix(ui): allow Cmd/Ctrl+P when terminal is focused (#211)

* fix(ui): allow Cmd/Ctrl+P when terminal is focused

xterm.js uses a hidden <textarea class="xterm-helper-textarea"> for
keyboard capture.  isEditableTarget() was treating it as a real editable
field, which suppressed all global shortcuts (Cmd+P, Cmd+N, etc.) when
the terminal had focus.

Exclude that element so app-level keybindings remain reachable.

* fix(ui): hide empty quick-open results area and reduce bottom padding

The results container was always rendered with pb-2, leaving visible
empty space below the search input when there were no results.
Conditionally render the results div only when there is content, and
reduce padding from pb-2 to pb-1.
