Resolve deprecated and missing dependencies for building.

[JoeStaff]

Summary

Restores a working Gradle build for the 1.12.2 branch by replacing dead/outdated Maven endpoints and pinning integration deps to resolvable coordinates. The mod again produces a normal deepmoblearning-*-universal.jar without vendoring those mods into the artifact.

What was wrong

• Legacy repos (e.g. old Curse/tehnut-style hosts) no longer resolve, so clean build failed on missing artifacts (Guide-API, Blood Magic stack, Matter Overdrive, CoFH/Thermal, etc.).

What was done

• Repositories: keep working mirrors (Forge, ModMaven, Covers1624, tterrag, etc.) and add CurseMaven for Curse-hosted jars.
• Dependencies: pin versions in ext maps / Curse file IDs where needed:
  • Thermal Foundation chain via CoFH-style coords (cofh:…, deobfCompile).
  • Blood Magic + Guide-API via CurseMaven (aligned with upstream 1.12 branch versions).
  • Matter Overdrive (Community Edition) + CLib via CurseMaven + com.astro.clib:CLib (as in upstream MO 1.12.2 Gradle).
• Source: re-enable integration classes excluded only to unblock compile (ThermalElementalMeta, MOAndroidMeta) and wire MobMetaFactory so Thermal / MO keys use the correct meta when those mods are loaded (optional at runtime).
