Remove Repeater titleFrom input type=text requirement.

[mjauvin]

Allow any input element as titleFrom, leave responsibility to user not to choose a type that doesn't make sense (e.g. button)

Summary by CodeRabbit

• Bug Fixes
  • Repeater widget more reliably derives collapse titles from a broader set of form elements (no longer limited to plain text inputs), improving display consistency.
  • Enhanced fallback logic when a collapse title isn’t found, so items show meaningful labels more often across varied input types.

Walkthrough

Introduce a dynamic selector in the repeater widget's getCollapseTitle so the title source prefers a computed target input (including non-text inputs when titleFrom points to a target) and falls back to select/ul or the item itself when no valid target exists.

Changes

Cohort / File(s)	Summary
Repeater Widget Selector Update modules/backend/formwidgets/repeater/assets/js/repeater.js	getCollapseTitle now initializes a selector variable and uses $(selector, $target).first() to choose the collapse-title source. When titleFrom matches a target, the selector expands to include non-text input types; otherwise it falls back to select/ul elements or the item itself.

In `@modules/backend/formwidgets/repeater/assets/js/repeater.js`:
- Around line 324-334: The code reads $target.length without ensuring $target is
defined when this.options.titleFrom is falsy; initialize or guard $target so
collapse handlers don't throw. Modify the block around this.options.titleFrom
and $target (the variables $target, selector, $item, and the subsequent
$textInput lookup) so that $target is set to $item by default (or check that
$target is truthy before accessing .length) before using it to find the selector
and creating $textInput.
