initial: split from gov-agreg — vreau.digital standalone platform

Moved from gov-agreg/src/pages/achizitii/* to root (drop prefix).
- 22 pages migrated, 127 files total
- All internal links: /achizitii/X → /X (176 occurrences fixed)
- AchizitiiLayout subnav rewritten: /X paths, top-right link to vreaudigital.ro hub
- BaseLayout new (vreau.digital branding, OG tags, site URL)
- astro.config.mjs: site https://vreau.digital, server output (was static)
- docker-compose: port 5096 (vreaudigital is 5095), container vreau-digital
- deploy.sh: paths /opt/vreau-digital, log /var/log/vreau-digital-deploy.log

Backend shared with gov-agreg:
- PostgreSQL satra (same schemas: seap, firms, anaf, anre, ...)
- Photon, Martin tiles
- Infisical /vreaudigital path (DATABASE_URL etc. shared)
