feat(source2): push all latest files - device labeling, help system, proxy docs, database isolation fix

- Added DOKUMENTASI-FILTER-PER-SITE.md (site isolation docs)
- Fixed start-with-env.js to force-load .env.production
- Fixed MONGODB_URI hostname from mongodb-netify to mongodb.prod.proit.id
- Updated .gitignore to exclude sensitive scripts and credential files
- Minor UI and labeling improvements
