refactor: observe call events from LocalCache instead of EventProcessor

Remove callManager injection from EventProcessor — let the existing
gift wrap pipeline consume and index call events normally. Instead,
observe new notes from LocalCache.live.newEventBundles in
AccountViewModel and route call signaling events to CallManager
from there. This keeps the EventProcessor clean and follows the
existing pattern for UI-layer event observation.
