Implement config panel for pages

[nkylstad]

Description

Current view when a page is "selected" (but no component is selected) is:

We should update this to allow editing of the following on page-level:

• page id (this is currently handled in the context-menu for the page)
• text resource for the page name
  • this should be represented as the page id as key in the text resource file. When that key is present, the page name from the text resource is automatically used in the navigationBar component.
• expressions on hidden prop - this will be covered by Implement expressions editor for hidden property on layout #12185 and is not part of this issue

Suggested design:

The implementation should follow the same design/setup as we are working on for components:

• ID (page name) always visible at the top
• Texts - for text resource bindings
• Dynamics - for expressions.
