Watch app: Fix connection issue upon fresh installs

[itsmeichigo]

Closes WOOMOB-742

Description

This PR fixes the connection issue between the app and the watch upon fresh installs.

Cause

The activationDidCompleteWith delegate method in WatchDependenciesSynchronizer is not triggered upon launch after the iOS app is first installed, causing the syncing method to fail assuming the watch session is not active.

Solution

• Replaces the isSessionActive property with the check for watchSession.activationState when syncing data on the iOS app.
• Adds tracking for when syncing fails - this might be useful if we see more reports about the connection between the iOS app and the watch.
• Adds a new label on the ConnectView on the watch for workaround when connection fails. This label is displayed only after the user taps "It's not working" button.

Testing steps

• Delete the Woo app on your iPhone if it's already installed.
• Download the prototype build in this PR.
• After installation completes, confirm that the watch app is installed. Open the app on your watch.
• Confirm that the app displays "Open Woo on your iPhone, log into your store, and hold your Watch nearby."
• Tap "It's not working" and confirm that "If the error persists, relaunch the app." is displayed.
• On the iOS app, log in to your test store.
• When login completes, check the watch and confirm that the connected store is displayed.

Testing information

Tested and confirmed with iPhone 16 Pro iOS 18.3 & Watch SE watchOS 11.1.

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Great job @itsmeichigo! The code looks good and tests well on my Watch SE (Gen 2). 🚢
