chore: Remove obsolete microservices directories and update all references

- Delete data-entry-app/ (1.6GB), reports-app/ (447MB), .auto-build-data/
- Saved ~1.4GB disk space (64% reduction: 2.2GB → 845MB)

Updated references across 38 files:
- .claude/rules/ paths: backend/modules/, src/modules/
- .claude/commands/validate.md: all validation paths
- docs/ (13 files): data-entry, telegram, README, CLAUDE.md
- scripts/ (3 files): backup-secrets, restore-secrets, test-docker
- security/ (2 files): git_cleanup, SECURITY_PROCEDURES
- deployment/ & shared/: updated all stale comments

All paths now reflect ultrathin monolith architecture:
- Backend: backend/modules/{reports,data_entry,telegram}/
- Frontend: src/modules/{reports,data-entry}/
- Shared: shared/{auth,database,routes}/
