Merge develop into feat/voice-channel

Resolved merge conflicts in:
- MessagesView.vue: Combined VoiceTimelineView component from voice channel feature with component list updates from develop
- actionCable.js: Merged call event handlers (incoming_call, call_status_changed) with copilot message event handler from develop
- message.rb: Combined voice call helper methods with send_update_event method from develop

All conflicts resolved while preserving functionality from both branches.
