revert(case): keep the bracket a solid frame (no FPC notch)

Browse Source 
Reverts the notch added in 6af959f. The flex U-turns off the glass's
left edge and returns inboard through the ~1 mm foam gap above the
bracket, then drops into the cavity through the aperture — it never
crosses the bracket plane, so the relief in the body's pocket wall is
enough. A solid frame also clamps that edge more evenly. Comment added
so the notch doesn't get reintroduced.
