Fix E905: remove Wire struct_/module_/c_stubs/ml_stubs from .mli
These Wire EverParse projection symbols belong in c/gen.ml (the
build-time 3D generator), not in the package's public API.
Affected: TM, TC, USLP, Space Packet, GPT, MBR, AOS, CLCW, PID1.
The codec itself remains the public API. The 3D/C generation is a
build artifact that downstream users never call directly.
