Tapping the headphones button in a conversation header used to start a
huddle straight away, so a stray tap (for example while reaching for the
members button) started a call and turned on the microphone. Now, when
no huddle is running, the button opens a "Start a huddle?" confirmation
with Cancel and Start huddle.

- Uses the shared `AlertDialog` the same way `MarkAllReadShortcut` does:
Cancel has initial focus, so pressing Enter or Escape doesn't start a
call.
- Joining a huddle that's already running, cancelling a connection,
showing the active huddle and leaving all stay one tap.
- The Solo chat-actions menu item ("Start a huddle") doesn't ask,
because choosing from a menu is already deliberate.
- Confirming goes through the launcher's existing `activate`, so if
someone else starts a huddle while the dialog is open, you join theirs.

Related to #2660, which moves the button further from the members
button. This PR is independent of it.

### Screenshots

Rendered from `tests/fixtures/huddles.html` in a DM with no huddle
running, after clicking the headphones button.

Before (the call starts connecting immediately):

### Validation

- `HuddleLauncher.test.tsx` covers the new behavior: Cancel gets focus,
Cancel doesn't start a call, Start huddle does.
- `tests/browser/huddles.spec.mjs` passes in Chromium and WebKit (43
passed). The four journeys that start a new call from the header now
click Start huddle.
- Full `vitest run`: 18,283 passed, 2 failed in unrelated media tests.
The HEIC dimensions test fails in this local environment, and
`MediaDownloadAction` passes when run alone.
- `tsc --noEmit` and `biome check` are clean.
- Not yet checked: the native desktop app, and a human trying it.
