feat(ocaml-sgp4): full deep-space SDP4 support + Vallado verification suite
Rewrite SGP4 propagator ported from python-sgp4 with deep-space (SDP4)
satellite support including lunar/solar perturbations and resonance
handling. Add canonical Vallado verification vectors (33 satellites,
~700 test points from SGP4-VER.TLE + tcppver.out).
Also: ocamlformat reformatting across ocaml-respond, ocaml-odm,
ocaml-cdm, ocaml-requests, ocaml-spacedata; update root.opam deps.
