Yeastar Linkus Mobile Client

1. Optimized number filtering: The system automatically removes "(" and ")" characters from outgoing numbers.
2. Fixed the following issues:
a. Received intercom calls continued ringing on the client when the caller hung up before the callee answered.
b. Incoming calls did not ring when missed Linkus call notifications remained in the mobile notification panel.
c. The client exited abnormally when accessing SMS sessions containing image attachments.
