…ual typing (TypeCellOS#2815)

When @ariakit/react updates its internal module structure (e.g. from
@ariakit/react-core to @ariakit/react-components), contextual typing
from external library component props can break, causing TS7006
'Parameter implicitly has an any type' errors in the Fresh Install
Tests CI workflow.

Add explicit type annotations to 5 callback parameters that depend on
external library types for inference:

- packages/ariakit/src/panel/Panel.tsx: setActiveId callback
- packages/ariakit/src/toolbar/ToolbarButton.tsx: onMouseDown callback
- packages/ariakit/src/panel/PanelFileInput.tsx: onChange callback
- packages/ariakit/src/badge/Badge.tsx: onClick callback
- packages/xl-ai/src/components/AIMenu/AIMenuController.tsx: outsidePress callback

All annotations use React/DOM built-in types (MouseEvent, ChangeEvent)
rather than library-specific types, making them resilient to future
dependency updates.

…nhandled DOMObserver errors (TypeCellOS#2816)

Tests that mount editors were not calling unmount() afterward, leaving
ProseMirror's DOMObserver timers active. When prosemirror-view is updated
to newer versions (e.g. 1.41.8 via fresh dep resolution), a dangling
setTimeout in DOMObserver.flush() fires after jsdom teardown, causing
'document is not defined' ReferenceError.

Add afterEach cleanup following the same pattern as transformPasted.test.ts.

* Memoized `actions` prop in consumers of `CommentEditor`

* Added e2e test, minor changes to existing tests

* refactor: extract actions into memo components with render prop pattern

- Change CommentEditor actions prop from FC to render prop (function returning ReactNode)
- Extract inline action components into separate memo-wrapped components
- Remove unnecessary useCallback/useMemo wrappers around render props
- React.memo on child components handles re-render optimization
