[Quality Q1] WearOS - Show offline indicator next to time text

[sztomek]

Description

This is a breakup task of the monstrous PR #4969
We now display an offline icon next to the time on most of the watch screens when the device is offline.
We dismiss this view when the user scrolls (horizontally) to the Now playing or Up next screens.

Fixes PCDROID-468

Testing Instructions

1. Build and install the wear app
2. Log in
3. Go airplane mode
4. Launch or open app again
5. Notice the offline indicator

initialValue = true makes isConnected emit true immediately even when the current networkStatus indicates no Wi‑Fi/Cell, which can momentarily show an incorrect “online” state and will break the existing ConnectivityStateManagerTest expectations (they currently assert the first emission is false when no networks are available). Consider keeping initialValue = false or deriving the initial value from the current network status so the first emission is accurate.

Suggested change

	initialValue = true,
	initialValue = false,

For accessibility, the content description string "Offline icon" describes the UI element rather than the state it conveys. Consider changing it to something that communicates meaning to screen readers (e.g., "Offline" / "No internet connection").
