* Fix descender clipping in sidebar user account section

Replace `leading-none` with `leading-tight` on the parent div wrapping
`displayTitle` and the "Studio" label inside `SidebarMenuButton`. The
child spans use `truncate` (overflow: hidden), so `line-height: 1`
clipped descenders (g, p, q, y, j) on user names. Same root cause and
fix as the model selector trigger.

* Add tests for studio text descender clipping

* [pre-commit.ci] auto fixes from pre-commit.com hooks

"""
Regression guard: descender-prone text spans in Studio must not pair
`leading-none` with `truncate` (overflow: hidden), which clips glyph
descenders (g, p, q, y, j) in real user-visible labels.
