Refactor Assets/Scripts: trim restating comments, minor structure cleanups

Sweep over 48 files (Editor/ excluded): remove comments that restate the
code, condense class summaries, fix three stale doc statements
(HsvColorPicker alpha bar, PaintHud layoutPrefab, MasterVolume
FallbackDefault). Inline two single-use wrappers (IsPointerOverUi,
BuildModes), drop an unused using, replace a magic literal with the
existing ParallaxBase constant, and convert ~10 UnityEngine.Object null
checks to the implicit-bool convention. No serialized fields, signatures,
RPC/NetworkVariable names, defaults, or #if blocks touched.

-/// Body position/rotation come from the NetworkTransform; this only carries the small extra state on

-/// model's child-local position (<see cref="PlayerCharacterController.MeshOffsetTarget"/>) — a tiny
-/// vector the owner eases continuously; the remote eases onto the replicated value so it doesn't
-/// tick-step (the body itself is already interpolated by the NetworkTransform).
