David Luzar 3947883063 refactor(editor): move text editing out of App into AppText (app.text) (#12195)
* refactor(editor): move text editing out of App into AppText (app.text)

A pure move of the text editing session, and of the text helpers around
it, out of App.tsx (14,250 → 13,478 lines) into App.text.ts. It sits next
to AppTextTool, which keeps the text tool's pointer interaction.

AppText holds:
- the session: startTextEditing (creates or picks the text to edit, and
  opens the editor), handleTextWysiwyg (the editor's lifecycle) and the
  open editor's submit handler
- the part of the canvas a typed or pasted text is kept within:
  getTextSidePanels, getTextViewportOffsets and getMaxTextWidth (paste,
  which stays in App for now, calls into them)
- where a new text goes: getTextCreationGridPoint and
  getTextWysiwygSnappedToCenterPosition
- the queries that find the text or container to edit:
  getTextElementAtPosition, getTextBindableContainerAtPosition,
  getSelectedTextElement, getSelectedTextEditingContainerAtPosition and
  isEditingTextContent
- the auto-resize handle: isHittingTextAutoResizeHandle and
  handleTextAutoResizeHandlePointerDown

Callers go through `app.text`, startTextEditing's included: no delegate
is left on App (no host or test used it). Beyond the move, `this.`
becomes `this.app.` for what stays on App, members called from outside
become public (App.deselectElements too), and the container ref and the
styles panel mode come in as dependencies, as AppViewport's do. The moved
code is identical to the removed, modulo those rewrites, whitespace and
trailing commas (checked mechanically).

* test(editor): click the text auto-resize handle through the pointer

The handle that turns a fixed-width text back into a growing one was only
covered through its action: nothing hovered or clicked it. Hovering it on
a selected wrapped text now shows the pointer cursor, and clicking it
unwraps the text, through AppText's hit test and pointerdown handler.
