fix(lighting): calibrate studio inspection lighting and add ACES/AgX tone mapping to prevent color blowout

[BharathASL]

Description

Configure ACES Filmic tone mapping and exposure 1.0 on all viewport WebGLRenderer instances to prevent specular and diffuse highlight blowout and color clamping on high-intensity surfaces.

Calibrate the studio-neutral preset as the default lighting setup (DEFAULT_LIGHTING_PRESET = "studio-neutral") using pure neutral white illumination (#ffffff) across key (1.0), ambient (0.4), fill (0.3), and rim (0.2) lights to ensure true neutral, unbiased color reproduction during texture inspection. Soften trailer-golden-hour directional sun intensity from 1.8 to 1.2 and ambient fill from 0.6 to 0.4 to prevent color burnout and preserve underlying texture hue across sunlit faces.

Expose configureToneMapping helper in lighting-presets.js supporting both ACES Filmic and AgX tone mapping profiles, update existing test expectations, and add verification tests in tools/test/lighting-presets.test.mjs and tools/test-e2e.mjs.
