feat(wear): add One-Handed Gestures demo and bump Wear Compose to 1.7.0-beta01

[ithinkihaveacat]

Summary & Goal

This PR adds Wear OS Material 3 One-Handed Gestures sample snippets for Android developer documentation (DAC).

With the release of androidx.wear.compose:compose-material3:1.7.0-beta01, the updated one-handed gesture APIs are now available in an official Jetpack release. As a result, this PR also updates the Wear Compose dependencies to 1.7.0-beta01, allowing these snippets to live directly in the standard :wear module without requiring snapshot subprojects or custom snapshot Maven repositories.

Important

Dependency Update: This change bumps the Wear Compose dependencies (wearComposeMaterial3, wearComposeFoundation, wearComposeMaterial, wearComposeNavigation3, and composeUiTooling) for all Wear samples in this repository from 1.6.2 to 1.7.0-beta01.

I don't think we should merge this since it bumps all samples to 1.7.0-beta01; we should wait until we get a 1.7.0 stable.
