Short Description and Why It's Useful

• Integrated the timeZone component from dxp-component into the application.
• Removed the setUserTimeZone and getAvailableTimeZones methods from userService and started using them from @hotwax/oms-api.
• Enhanced the setUserTimeZone action, making it synchronous for improved functionality.
• Updated the settings section by replacing the timeZone settings and incorporating the DxpTimeZoneSwitcher component from dxp-components.
• Updated the UI to display both the selected timezone and the browser timezone.

The modal does not close after the first selection of the time zone. Instead, it closes after the second selection. The same behavior occurs when using the close button on the modal.

@R-Sourabh This issue is fixed in #275, please check after updating this branch with main.
