fix: Restore all files lost during destructive rebase

Browse Source 
A previous `git pull --rebase origin main` dropped 177 local commits,
losing 3400+ files across admin-v2, backend, studio-v2, website,
klausur-service, and many other services. The partial restore attempt
(660295e2) only recovered some files.

This commit restores all missing files from pre-rebase ref 98933f5e
while preserving post-rebase additions (night-scheduler, night-mode UI,
NightModeWidget dashboard integration).

Restored features include:
- AI Module Sidebar (FAB), OCR Labeling, OCR Compare
- GPU Dashboard, RAG Pipeline, Magic Help
- Klausur-Korrektur (8 files), Abitur-Archiv (5+ files)
- Companion, Zeugnisse-Crawler, Screen Flow
- Full backend, studio-v2, website, klausur-service
- All compliance SDKs, agent-core, voice-service
- CI/CD configs, documentation, scripts

# Zeugnis-System - Architecture Documentation
## Overview
The Zeugnis (Certificate) System enables schools to generate official school certificates with grades, attendance data, and remarks. It extends the existing School-Service with comprehensive grade management and certificate generation workflows.

## Zeugnis Workflow (Role Chain)
The certificate workflow follows a strict approval chain from subject teachers to school principal:

## German Grading System
| Grade | Meaning | Points |
|-------|---------|--------|
| 1 | sehr gut (excellent) | 15-13 |
| 2 | gut (good) | 12-10 |
| 3 | befriedigend (satisfactory) | 9-7 |
| 4 | ausreichend (adequate) | 6-4 |
| 5 | mangelhaft (poor) | 3-1 |
| 6 | ungenuegend (inadequate) | 0 |
### Grade Calculation
```
Final Grade = (Written Weight * Written Avg) + (Oral Weight * Oral Avg)
Default weights:
- Written (Klassenarbeiten): 50%
- Oral (muendliche Note): 50%
Customizable per subject/student via UpdateGradeWeights endpoint.
```
## Integration with BYOEH
The Zeugnis system can optionally integrate with BYOEH for:
- AI-generated certificate remarks
- Template suggestion based on student performance
- Feedback text generation (`/certificates/feedback/:studentId`)
## Security Considerations
1. **RBAC Enforcement**: All certificate operations check user role permissions
2. **Tenant Isolation**: Teachers only see their own classes/students
3. **Audit Trail**: All grade changes and approvals logged
4. **Lock Mechanism**: Finalized certificates cannot be modified
5. **Workflow Enforcement**: Cannot skip approval steps
## Future Enhancements
- [ ] PDF template editor (LaTeX/HTML)
- [ ] Bundesland-specific templates (all 16 states)
- [ ] Kopfnoten (head grades) support
- [ ] Digital signatures for certificates
- [ ] Parent portal access to certificates
- [ ] Archive/retention policies
