Merge branch 'main' into issue-2977

#### Description

- pages that hardcoded `100vh` minus a guess at what sits above them
came out taller
than the pane they live in, which showed up as scroll that should not be
there. they
  now take what the layout gives them.
- most of the `100vh` in the app turned out to be harmless.. either
flex-shrink absorbs
it or the pane scrolls anyway. those are left alone, only the ones with
a real symptom
  are changed here.
- alert rules and triggered alerts also needed the AlertList tabs chain
to hand height
  down, that page uses antd `Tabs` directly instead of `RouteTab`.
- licenses, status and support pages had `max-height: 100vh` with
`overflow: hidden` and
no inner scroller, so anything past a viewport was clipped with no way
to reach it.
  removed the cap on all three.
