Add "Lock Width/Height/Ratio" actions to on-canvas crop tool context menu
What: This adds three additional toggles - Lock Width/Height/Ratio - (and a separator to group them) to the so far sparsely populated on-canvas right-click context menu of the Crop tool.
Why: This speeds up various cropping workflows by making the lock toggles available directly on-canvas at the current cursor location.
Test Plan
Toggle the Lock Width/Height/Ratio state from both the Tool Options Docker and the On-Canvas Context Menu, checking if the state is correctly synced between the two and applied to the tool.
