Take disabled off the FAB, and fix its extended metrics

M3 is explicit twice over — never disable a FAB, remove it instead — and the
prop painted the full disabled treatment with nothing warning against it. It is
gone; hiding the FAB is the documented answer. The extended FAB's icon-to-label
gap goes to M3's 16dp at md and 20dp at lg, the small one takes the baseline's
80dp minimum width, and the root gains a `data-fab` hook for a place that draws
a nested FAB its own way. Plan step 18, actions.md ACT-08, ACT-16, ACT-31.

There is no `disabled`: M3 says to remove a FAB whose action is unavailable, so hide it instead. `data-fab` on the root lets a place restyle a nested FAB (a rail flattens it to elevation 0).
