Unify Transform and Constraint Axis UI + UX

The ''Constraint Axis during Transform Tool Operator'' and ''Transform Axis using Knife (other) Operator'' are not in sync from UIX perspective.

💡Proposal ⌁ Generally Helpers (in this case, 'Axis') are usually represented as dotted lines for better ux sake, So Both Trnsfm Axis and Constrain Axis should be in sync visually and the visual itself (.i.e. the uix) of the axis shoud be a DOTTED AXIS COLORED LINE

The Dotted Line Axis Drawing Principal can/should be applied all around relatively

Code for drawing Dotted Line already exists inside Blender
