Initial commit: MetaVox loadtest playbook

Ansible playbook voor het opzetten van een MetaVox loadtest omgeving:
- 50 teamfolders met 10.000 bestanden elk (500K totaal)
- 100 metadata velddefinities (10 teamfolder + 90 file-level)
- 3-niveau mappenstructuur (10 hoofdmappen x 3 submappen)
- ~43M metadata records via directe MySQL inserts
- Geoptimaliseerde database indexes (7 redundante indexes gedropt)

Gebruikt directe filesystem writes en MySQL inserts i.p.v. WebDAV/API
voor maximale performance.
