fix sliverfixedextent with sliverchildbuilderdelegate does not correct calculate max scroll extent (#39142)

This changes the behavior of text fields, Material buttons, and Chips so that if they are disabled they lose focus. Before this change, it was possible to disable a control and then use focus traversal to reach it anyhow, and in the case of text fields, enter text into a disabled field.

Fixes #33985

Use the entire appBarTheme from the showSearch delegate for the search pages appBar theme, rather than just a select set of fields.

The Text in the Transform.scale example is "Bad Ideas", which could be confusing as example code. This PR replaces it with something more random.
