Switch mods to per-folder auto-discovery and resourcepack to single zip

- PackDefinition: replace mods[]/resourcepacks[] with modsFolder (string) + resourcepackPath (string); drop PackAsset
- Editor: replace dynamic add/remove lists with two single inputs; remove the now-dead JS for adding/removing rows
- Server: expose GET /file/mods/<folder>/index.json that returns the list of .jar names; folder name restricted to [a-zA-Z0-9_-]+
- Installer: fetch the listing JSON and download each jar from /file/mods/<folder>/<file>.jar; download the single resourcepack from /file/resourcepacks/<file>.zip directly into resourcepacks/
