Saxon FletcherandClaude Opus 5 7880c2f079 fix(studio): explorer chat and notebook layout refinements (#50453)
Five layout fixes across Explorer chat, notebooks, and the sidebar.

### Chat

- **Conversation fade overlapped the scrollbar.** The top and bottom
gradients are positioned against the conversation's padding box, which
includes the scroll container's scrollbar gutter, so `inset-x-0` painted
them over the scrollbar. They now stop at the conversation's content
gutter, which `Conversation` owns for both the content and the fades.
- **Composer background bled past the input's radius.** The form paints
the surface behind the textarea but had no radius of its own, so its
square corners showed outside the `rounded-lg` input. It now shares the
radius.
- **Message parts used two different widths.** Wide parts come down to
`max-w-3xl` so every part shares a column, matching `AssistantQueryCell`
and `AssistantNotebookPreview`. `isWide` / `isWideMessagePart` stay in
place with both widths equal, so a part can diverge again later without
rebuilding the mechanism.

### Notebooks

- **Cell controls sat at the container edge.** Each cell centred itself
at its own max width while the grip and add-cell button stayed at the
far left of the full-width row, leaving a large gap. `SortableSection`
takes a `sectionWidth` and carries its control gutter twice — once as
the controls, once as padding on the other side — so the section stays
centred with its controls immediately beside it. Cell widths are
unchanged (prose `48rem`, query `72rem`); set them equal and the two
cell types' controls line up on their own.

The controls stay in flow rather than floating in an outside gutter, so
on a viewport narrower than the cap the row just fills the space instead
of clipping the controls into the padding.

### Sidebar

- **Search icon didn't line up with the menu row icons.** The row box
already sits flush with the search input's box, so rows moved from
`pl-3` to `pl-2` to put their icons on the same 8px offset the search
icon uses. Spacing between the input and the list now matches the 12px
side padding.

### Testing

`pnpm --filter studio run typecheck`, Prettier, and 378 tests across
`Explorer`, `ProjectHome`, `AIAssistantPanel`, and `ExplorerLayout`
pass. ESLint warning counts are unchanged from master.

These were reasoned from layout rather than checked in a browser, so
they're worth a look on a preview before merge.
