soma test: instrument 7 more demos for permutation runner (composite + toggleables batch)

Adds `data-perm-step` + `<meta name="perm-axes">` + perms seed to:

- **accordion** — expand item-1 → switch to item-2. `?perm.value=item-1`
  seeds the Provider's value array. `dir` axis.
- **listbox** — select apple (first) → select apricot. `?perm.orientation`
  flips the layout, already wired. Items in a loop use conditional
  `data-perm-step` by index. `dir,orientation` axes.
- **tree-view** — select readme → select license under the expanded docs
  branch. `?perm.expanded=docs&perm.selected=readme` seed. `dir` axis.
- **combobox** — open via trigger (Combobox.Trigger). `dir` axis only —
  typing / selection is left to v4 per-component value enumeration.
- **menubar** — open File menu → close via Escape (mode=key, 500ms settle).
  `dir` axis.
- **toggle** — press Bold toggle (inside Field.Provider integration
  example). `dir` axis.
- **toggle-group** — press left → press center (single mode). Added
  `aria-label="Text alignment"` to silence the A4 DEV warning that now
  fires (shipped in batch 10 of audit 2026-04-21). `?perm.value=bold`
  preselects. `dir,orientation` axes.

## Deferred in this batch

- **context-menu** — needs `contextmenu` event (right-click). Requires a
  `data-perm-mode='contextmenu'` extension to the runner. Future batch.
- **navigation-menu** — hover-driven only. Same future-batch treatment as
  Tooltip has with `data-perm-mode="focus"` + long settle.

## Coverage delta

- Before: 8 demos · 19 variants · 62 steps.
- After:  15 demos · 35 variants · 106 steps.

~1.7× jump in a single batch. Tabs still leads with 4 variants (adds
`orientation` + `disabled` axes); ToggleGroup, Toolbar, Listbox each have
3 variants.

## Verification

- `npm run check`: 0 errors in soma/morfo/test-route scope.
- `npm run smoke`: 65/65 routes.
- `npm run morfo:check`: 66/66 morfos.
- `npm run perm:check`: 15/15 demos · 106 steps · 35 variants.
