Harden E2E UiAutomator text-wait helpers against recomposition (#6383)

* Make Wait.kt's text-wait resilient to recomposition.

Rework UiObject2.waitForText into BySelector.waitForText that re-resolves the selector on each poll, absorbing StaleObjectException from mid-poll recomposition. Bypass the findObject() extension (which lies about nullability) by calling device.findObject(this) directly. Accept a mustBeEqual flag so the channel-preview assertion can substring-match and avoid timing out when the rendered preview has trailing whitespace. Update the 4 robot call sites.

* Throw descriptive error from waitToAppear on timeout.

waitToAppear and waitToAppear(withIndex) previously NPE'd via the findObject() extension's non-null declaration when the selector didn't match before timeout. Now they throw IllegalStateException with the selector, timeout, and (for the indexed overload) matched object count.

* Fix stale channel-preview test to match post-#6212 behavior.

Since #6212 (2026-03-05), the channel preview shows "Message deleted" when the last message is soft-deleted instead of falling back to the previous message. Rename the test, update the assertion, and add a dedicated assertDeletedMessageInChannelPreview helper.

* Use waitForText for remaining text asserts and throttle its poll loop.
