## Summary
- Add `align-items: center` to tab list `StyledContainer` so the
overflow button aligns vertically with tabs
- Remove ineffective `> * { height }` hack from `TabMoreButton` (was
being reset by `all: unset` in `StyledTabButton`)
## Test plan
- Open a record detail page with enough tabs to trigger the "+N More"
overflow
- Verify the overflow button is vertically centered with the visible
tabs
