Crash on desktop startup from null persisted tab #39644

Description

The desktop app can crash during startup when persisted tab state contains a null entry.

Error

TypeError: Cannot read properties of null (reading 'type')

The stack trace may point to either tabKey or currentTab/matchRoute.

Impact

• Reported by multiple Discord users.
• Reproduced on desktop version 1.18.9.
• Prevents the application from loading.

Expected behavior

Malformed persisted tab entries should be discarded during hydration instead of crashing the renderer.

Additional context

The persisted tabs migration currently preserves null and malformed array entries. Validating and repairing the array during migration prevents the crash.
