Subject: [PATCH] feat: fixture de persistent context para preservar E2EE keys
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Nuevo fixture que crea un worker-scoped persistent browser context
compartido entre tests. A diferencia de storageState, preserva IndexedDB
donde Element Web guarda las crypto keys de E2EE.

Incluye handleElementDialogs() que maneja:
- "Element is open in another window" → click Continue
- "Missing session data" → error informativo
- Espera rooms sidebar como señal de sesion cargada
