Pull Request Overview

A PR to tabify the mirror panel on the right side of the QGIS window and dynamically set its width based on the main map canvas, while also introducing utility functions to work with right dockwidgets.

• Added functions get_right_dockwidgets and set_panel_width in utils.py.
• Updated process.py to compute and apply the panel width and tabify dock widgets for mirror comparison.

• There is an inconsistency in naming with mirror_widget used here versus mirror_dock_widget used earlier. Use a single consistent variable name to avoid confusion.
