* fix: Midpoint highlight color in dark mode
The highlighted binding midpoint hardcoded rgba(3, 93, 161) for dark mode,
the pre-filter color from when the interactive canvas was inverted by a
CSS filter. The canvas now draws post-filter colors directly, so it
rendered dark blue. Use BINDING_HIGHLIGHT_RGB like the rest of the binding
highlight.

* fix: Show binding midpoints like before the hit test rework
The binding highlight drew all four midpoints for any suggested binding,
including simple arrows with the cursor deep inside the element. Restore
the previous visibility: simple arrows show no midpoints from inside, and
from outside only the one nearest the cursor once it gets near; elbow
arrows show all of them. The highlighted midpoint still comes from the
suggested binding, so it sits where the arrow actually snaps.

* fix: Images and locked opaque elements occlude binding
Only filled shapes hid the elements behind them from binding. Images now
count as opaque, and locked opaque elements hide what is behind them too
(they still can't be bound to). Frames are future-proofed: once they get
a background, an opaque frame hides the non-children behind it without
ending the search, as its children sit just below it in z-order.

* refactor: Add DEFAULT_ZOOM for computations without an editor zoom
Replace the scattered { value: 1 } as Zoom / AppState["zoom"] casts used
as a zoom fallback (elbow arrow routing, transform, element rendering,
binding repair on restore, tests) with a shared frozen constant.
