Approval cards show again: the buttons no longer throw, the command is the item's detail

An agent chat's bash approval left "Waiting for you to allow bash…" with no card: cardOf()
called append(actions, a, b, c) while append() took one array, so `children.flat` threw for
every approval and plan card (questions used el.append and worked). renderCards() had already
unhidden #cards, which stayed empty. append() now takes children as rest arguments too.

- The editable command is `detail` (services/device_link.py puts the fixed "Run a command" in
  the title); it is sent back as the item's text only when changed. Non-editable approvals
  show the title and the device's input. `purpose` ("It says: …"), `reason` and the asking
  subagent (`job`) are shown, as on the web page.
- renderCards() keeps a card already on the screen (by id) instead of drawing every card again
  on each `ask` frame, which the server re-sends whenever the countdown changes; a card that
  cannot be drawn shows the error instead of an empty box.
- tests/ui/: headless harness with a mocked Tauri bridge; five A1 cases (device bash card
  shows and is visible, Allow/edit/Deny post to /chats/{id}/interactions/{card}, redraw keeps
  edits, reopen gets the card from the stream's first pass, 390 px).

 ## [Unreleased]
 
+### Fixed
+
+- **Approvals show again.** An agent asking to run a command, edit a file or carry out a plan
+  stopped with "Waiting for you to allow bash…" and no card to answer it: drawing the card's
+  buttons failed, and the space for it stayed empty. Stopping and asking again gave the same.
+  Now the card shows, with the command in the box to correct before it runs (it used to show the
+  words "Run a command" there instead), what the model says it is for, why it is asking, and which
+  subagent asks when one does. A card already on the screen is kept as it is while the reply goes
+  on, so a command being corrected or an option picked is no longer lost when the server sends
+  the list again; a card that cannot be drawn says why instead of leaving an empty space.
+
+### Added
+
+- `tests/ui/`: the page under a headless browser against a stand-in for the app's bridge, with
+  the server's answers as a table (`node tests/ui/run.mjs`, needs Playwright and a Chromium).
