Reorganize repo: compartmentalize scripts by client/project

Move 150+ scripts from root and scripts/ into client/project directories:
- clients/dataforth/scripts/ (110 files: AD2, sync, SSH, DB, DOS scripts)
- clients/bg-builders/scripts/ (14 files: Lesley mgmt, Exchange, termination)
- clients/internal-infrastructure/scripts/ (10 files: GDAP, Gitea, backups)
- projects/msp-tools/scripts/ (9 files: CIPP, MSP onboarding, Datto)
- projects/gururmm-agent/scripts/ (3 files: API test, JWT, record counts)
- clients/glaztech/scripts/ (1 file: CentraStage removal)

Also reorganized:
- VPN scripts → infrastructure/vpn-configs/
- Retrieved API/JS files → api/
- Forum posts → projects/community-forum/forum-posts/
- SSH docs → clients/internal-infrastructure/docs/
- NWTOC/CTONW docs → projects/wrightstown-smarthome/docs/
- ACG website files → projects/internal/acg-website-2025/
- Dataforth docs → clients/dataforth/docs/
- schema-retrieved.sql → docs/database/

Deleted 24 tmp_*.ps1 one-off debug scripts (preserved in git history).
Root reduced from 220+ files to 62 items (docs + directories only).
