feat(CallScreen, FloatingCallWindow, callStore, wsService): enhance call status handling and UI updates

- Updated call status messages to include 'calling', 'reconnecting', and 'failed' states for better user feedback.
- Improved video handling logic in CallScreen to use currentCall.isVideoEnabled for local video display.
- Enhanced callStore to manage new call statuses and ensure proper timeout handling during 'calling' state.
- Added a method in wsService to retrieve the active call state after WebSocket reconnections.
- Refactored FloatingCallWindow to reflect updated call status messages for consistency across components.
