Bug 修复

Extension: Fixed the extension configuration loss issue: After upgrading the PBX, the Open Contact URL Using Custom Popup URL feature that was originally enabled for the extension's Linkus Desktop Client became disabled; the previously configured related values were cleared and could not be auto‑populated when the feature was re‑enabled.

Trunk: Fixed the SIP INVITE request issue for register trunk: For a register trunk configured with the ITSP domain and the Use Registered Target IP for SIP Requests option disabled, the SIP INVITE message contained an IP address instead of the intended domain name.
Auto Provisioning: Fixed the reprovision issue: After reprovisioning IP phones that had been provisioned to the PBX via custom advanced Auto Provisioning templates, SIP registration failed.
WhatsApp Message Channel: Fixed the contact display issue: After upgrading the PBX, when extension users sent messages to contacts via the WhatsApp channel on Linkus clients, the contact names failed to appear in both the chat list and session window.
Hot Standby: Fixed the Hot Standby issue: If the operating system of the Primary Server hosting the PBX is Ubuntu 24.04, the system's default temporary‑file cleanup policy automatically deletes files in the /tmp directory. This causes the Primary Server status to display as Stopped and Hot Standby did not work.
