Pull request overview

This PR refines the UI for panel and auxiliary bar maximization/restoration by introducing separate icons for maximize and restore states, and improving the menu item registration patterns.

Changes:

• Introduced dedicated restore icons (restoreIcon) for both panel and auxiliary bar to differentiate from maximize state
• Refactored panel's toggle maximize action to use separate menu registrations for maximize and restore states instead of a toggled property
• Removed dependency on panel's close icon from auxiliary bar, making it independently defined
• Enhanced auxiliary bar's close button to hide when maximized and appear as an alt action on the restore button

• The localization key 'minimizePanel' is inconsistent with the English text "Restore Panel Size". Consider updating the localization key to 'restorePanel' or 'restorePanelSize' to match the actual text and align with the pattern used in auxiliaryBarActions.ts where 'restoreAuxiliaryBarTooltip' is used for similar functionality.
