fix(app): paint a smaller send and stop disc inside the touch hit frame (#8891)

Under touch sizing the composer's send and stop buttons filled their whole
44pt hit frame with color, so they outweighed every unpainted control in the
toolbar. The trigger keeps the 44pt frame and now paints a 36pt disc
(TOOLBAR_DISC_SIZE) centered inside it. Pointer sizing paints 28 inside 28, so
desktop is unchanged. The voice button's recording fill follows the same rule.

Controls come in two sizes, defined once in `control-geometry.ts`. The default is the right size almost everywhere — pages, dialogs, forms, settings rows, the setup flow — so don't pass a size. It is 32px tall where a pointer drives it and 44px where controls are touch-sized, so every touch control meets the iOS HIG's 44pt hit region. `sm` is 28px pointer and 32px touch, with `fontSize.sm` labels, and is for tight chrome only: toolbars, nested settings rows, dense inline row actions. A `size="sm"` on an ordinary page or dialog is wrong, and so is choosing a size from `useIsCompactFormFactor()`.

It is 32px tall where a pointer drives it and 44px where controls are touch-sized, so every touch control meets the iOS HIG's 44pt hit region. The hit region is not the painted area: a filled toolbar control such as the composer's send or stop keeps the 44pt frame and paints a 36pt disc inside it (`TOOLBAR_DISC_SIZE`), so it does not outweigh its unpainted neighbours. `sm` is 28px pointer and 32px touch, with `fontSize.sm` labels, and is for tight chrome only: toolbars, nested settings rows, dense inline row actions.

One gate, `resolveControlSizing`, picks touch or pointer sizing: touch when the layout is compact or the device has a touch screen. An iPad with the sidebar docked is wide and touch-sized; a desktop is pointer-sized; a phone is both compact and touch. The touch-screen fact is read once at startup (`hasTouchScreen` in `hooks/use-fine-pointer.ts`), so attaching a mouse or keyboard to a tablet never shrinks its controls. Stylesheets take sizes from `bySizing({ touch, pointer })`, which resolves to a breakpoint value, so a caller never sees which sizing it got. Rows, icon buttons and icon slots take theirs from `styles/density.ts`, which uses the same gate. An `{ xs, md }` literal for a hit target or glyph is wrong: on an iPad it yields the pointer size.
