Revízny systém - kompletná implementácia

- Backend: CRUD revízií, schedule endpoint (agregovaný plán), skip revízia, stats
- Shared utility revisionSchedule.ts - centralizovaná logika výpočtu cyklov
- Equipment detail s revíznym plánom, históriou a prílohami
- Frontend: RevisionsList s tabmi (nadchádzajúce/po termíne/vykonané/preskočené)
- Pozičné labeling cyklov (eliminuje drift 4×90≠365)
- EquipmentRevisionSchedule model (many-to-many typy revízií)
- Aktualizovaná dokumentácia HELPDESK_INIT_V2.md
