Replace production servers with test-only servers and mods

- Remove all 9 existing production server configs
- Create 5 Forge test servers (1.7.10, 1.12.2, 1.16.5, 1.20.1, 1.20.4)
- Create 3 Fabric test servers (1.20.1, 1.20.4, 1.21.1)
- Generate minimal test MOD JARs (metadata-only, no Java code)
- Add create-test-mods.js script for JAR regeneration
