Breaking: #69699 - TCA ctrl typeicons removed

See Issue #69699

Description

The TCA['ctrl']['typeicons'] key has been removed.

Impact

If still used, a fallback default icon may be displayed instead.

Affected Installations

Searching for typeicons keyword should reveal extensions using this functionality.

Migration

Until further works on the icon API have been finished, TCA['ctrl']['typeicon_classes'] should be used as documented in the TCA reference.
