Rebuild the orbital verification field

[JROChub]

What changed

• rebuild the Three.js Earth with deterministic cloud cover, sun-aware atmosphere, improved day/night grading, and clearer orbital depth
• add live validator/city labels, proof-orbit state, animated trails, radar ripples, topology glow, and sparse proof constellations
• keep mobile, landscape, tablet, and desktop layouts collision-free while preserving every verifier interaction
• add orbital-map construction contracts and a versioned deployment entrypoint

Performance

• replace per-fragment procedural cloud noise with a deterministic precomputed texture
• collapse label projection to one layout read per frame and remove per-frame orbit allocations
• match or slightly exceed the prior production scene under the same SwiftShader baseline

Validation

• all six proof modes and claim/URL/seed portal flows
• desktop, wide, compact, tablet, mobile, and mobile-landscape Playwright checks
• direct canvas nonblank, variance, and motion checks
• WebGL-disabled fallback
• observatory, stream, status, campaign, and release-consistency contracts
• JavaScript syntax, diff whitespace, and bidi-control scan
