Migrate to modern ReScript .res.js suffix and remove patch

Following Alex Fedoseev's recommendation, migrated from .bs.js to .res.js
suffix, eliminating the need for patching @glennsl/rescript-json-combinators.

Changes:
1. Updated bsconfig.json suffix from .bs.js to .res.js
2. Removed patch for @glennsl/rescript-json-combinators
3. Updated webpack config to resolve .res.js extensions
4. Rebuilt ReScript - all files now generate with .res.js suffix
5. Removed duplicate RescriptShow/ror_components directory
6. Updated patches/README.md to document migration

Why this is better:
- ✅ No patch maintenance burden
- ✅ Follows modern ReScript v11+ conventions (.bs being phased out)
- ✅ Compatible with future ReScript versions
- ✅ Works with all ReScript packages out of the box
