feat(wear): add Compose wearable features

[Foxpace]

Adds the Wear OS domain and Compose presentation layers for recording, sensor display, menus, and phone launch.

What was added

• Wear measurement control, permission, sensor-query, observation, and sync use cases.
• Dashboard, menu, and phone-launch contracts, screens, and view models.
• Reducer and view-model unit tests with a coroutine dispatcher rule.

How it works

Wear screens follow the same intent-state-effect pattern as the phone application. View models invoke domain use cases to discover sensors, observe live values, control recording, transfer completed files, or request that the paired phone opens, then reduce results into immutable UI state.

Superseded by #46, which targets master and shows the final current tree. Closing this stacked layer so review stays on the consolidated diff; this PR remains available as history.

Stack restored at the author's request. This PR is again part of the original 31-layer refactor chain. The architecture work continues as stacked PRs #47 through #54; consolidated PR #46 is superseded.
