feat(browser): rework element annotation and picker toolbar

Element annotation is now free-text: dropped the Fix/Change/Question/
Approve intent pills and the intent field, so the user just says what
they want. The card uses the shared Button and is titled "Annotate
element".

Toolbar: the element picker and DevTools are no longer dev-gated and
work in prod; DevTools uses a wrench icon, and the old clipboard "grab"
is now a Camera "Screenshot element" tool. Each toolbar button
highlights only its own mode, and the copy toast reflects whether a
screenshot image was actually captured.
