Description

Current chips render their actions as a <craft-action-menu> with a slot="invoker" button. Only the deprecated disclosure-menu fallback still renders .btn.action-btn. getLastActionBtn() looked for .action-btn only, so on current chips it found nothing, and once an element select input was full, getNextLogicalFocusElement() had no focus target.

 getLastActionBtn()
-  container.querySelectorAll('.action-btn')
+  container.querySelectorAll('craft-action-menu > [slot="invoker"], .action-btn')

The same selector goes into both copies: core BaseElementSelectInput and the Yii adapter's Craft.BaseElementSelectInput, which still returns a jQuery collection (.find(…).last()).

element added, field now full
  focusNextLogicalElement()
    getNextLogicalFocusElement()
      getLastActionBtn()   → the last chip's action menu invoker (was null / empty)

This also gives the selector modal its triggerElement on a full field. #20652's container fallback for triggerElement in getModalSettings() stays as a last resort for full fields with no chip action menu, such as when showActionMenu is off. Its test "gives a full field’s modal its container to return to" boots a full field whose chips get action menus, so with this change it gets the last chip's invoker instead of the container; that test's fixture needs chips without action menus (e.g. showActionMenu: false) once both land.

Evidence

Unit tests: a full field's next focus target is the last chip's action menu invoker, in both copies.

• Before: expected null to be <craft-button …> (core), expected +0 to be 1 (adapter)
• After: both pass.

Browser: a server-rendered single-relation element select (limit 1, the UI kitchen sink's HTML renderer), choosing an entry with the keyboard:

• Before: document.activeElement is <body>.
• After: document.activeElement is the chip's <craft-button slot="invoker" aria-label="Actions">, with a visible focus ring.

The workbench doesn't load the Yii adapter, so the adapter copy was checked through its jQuery unit test only.
