test(expo): Isolate native token bootstrap in sync tests

[wobsoriano]

Description

The native client sync tests in Expo were all starting with getClientToken() returning a device token by default. That meant tests which were trying to verify event handling could also get an unrelated bootstrap token write in the background.

This changes the default mock to return null and keeps the native token setup only in the tests that are actually covering recovery from a native token.

📝 Walkthrough

Walkthrough

The suite-level beforeEach default for mocks.getClientToken is changed from 'native-client-token' to null, removing the need for per-test mockResolvedValue(null) overrides across ten tests. One waitFor assertion for __internal_reloadInitialResources is removed and mocks.tokenCache.getToken is explicitly set to null in one test. A changeset file is added.

Native-client sync test mock consolidation

Layer / File(s)	Summary
Shared default and per-test cleanup packages/expo/src/provider/__tests__/ClerkProvider.nativeClientSync.test.tsx, .changeset/stable-expo-native-sync-tests.md	beforeEach now resolves getClientToken to null; ten individual tests drop their redundant mockResolvedValue(null) lines. In the "native clears the device token" test, tokenCache.getToken is explicitly nulled and the waitFor(__internal_reloadInitialResources) assertion is removed. Changeset entry added.

🐇 Null is the default, no need to repeat,
Ten mock overrides gone — how neat!
The beforeEach sets the tone,
Each test need not moan alone.
Less code, same truth — a bunny feat! 🌿
