Patrick Plate 1a0a56a626 chore(java): consolidate mss-failsafe to single canonical copy
Replace the stale multi-module java/mss-failsafe skeleton (old user-management
prototype) with the active single-module machine-safety inspection app that was
living in its own standalone repo at the repo root.

- Remove old java/mss-failsafe/ multi-module tree (mss, userdata, userManagement,
  mssfailsafe.datalayer, mssfailsafeWeblayer) incl. committed build artifacts
- Add the active app (PrimeFaces 11 / JSF 2.3 / Hibernate 5.6 / iText / POI)
  flattened into java/mss-failsafe/ as the only mss-failsafe in git
- Working tree captured = master tip 2a142b5 + in-progress uncommitted work
  (incl. .github/*.instructions.md AI-context files)
- Archive the standalone repo's 33-commit history in GIT_HISTORY_ARCHIVE.md
  since its .git was not migrated

This is the source of truth / base for the upcoming upgraded rewrite.

# Coding Guidelines Instructions
## Naming
- Manager: *Manager
- Controller: *Controller
- Entities: Singular Substantive
- Negative IDs: temporäre Objekte
## Style
- 4 Spaces
- Logger statt System.out
- Deutsche UI-Texte, Englisch im Code
## Error Handling
- Log + Rückgabe (bestehend); für neue komplexe Logik optional BusinessException
## Persistenz
- Neue Entity: id == null vor persist
- refresh(entity) nutzen um Lazy Collections zu initialisieren
## Transaktionen
- Schreibmethoden: @Transactional (oder rely auf EJB Container)
## Performance
- Sammeloperationen: saveAll(Collection<T>)
## UI
- PrimeFaces Dialoge schließen mit closeDialogs
- Negative IDs in Listen bis Sammelspeichern
## PDF
- Neue Funktionen nur mit iText7 API
## Tests (Empfehlung)
- CRUD Manager Tests
- Klon & Fragebogen Zuordnung
## Anti-Pattern
- Logik nicht direkt im Controller wenn generell wiederverwendbar
- Keine duplizierten Query Strings -> Named Queries
