Odoo can now recognize when users access it through the Android Odoo Mobile app. This helps the web experience adapt more reliably for mobile app users and supports better app-specific behavior.

This commit adds a proper way to detect the Android OdooMobile app using
the User-Agent.

Mobile VoIP calls now use the phone's normal default audio device consistently across the Odoo app and mobile browser. Users can also switch audio input during calls, making it easier to move between speakerphone, earpiece, or connected Bluetooth/USB devices and resolving an issue where answered calls were forced to loudspeaker.

Issue: - can't able to create timesheet from grid cell even timesheet date is valid. Cause: - timesheet creation is checked for existing timesheets not the timesheets that user
