docs: Session log update - VPN setup and DOS deployment completion

Updated comprehensive session log documenting:

## DOS System Completion (Part 1)

**Major Milestones:**
- Located and documented AD2 sync mechanism (Sync-FromNAS.ps1)
- Deployed 6 DOS batch files to production (AD2)
- Created DEPLOY.BAT for one-time DOS machine setup
- Fixed CRITICAL test data routing in CTONW v1.2
- Added root-level file sync (UPDATE.BAT, DEPLOY.BAT to T:\)

**CTONW v1.2 Critical Fix:**
- Separated software distribution (ProdSW) from test data (LOGS)
- Problem: Test data uploaded to ProdSW, but sync expects LOGS folder
- Solution: Separate workflows - programs to ProdSW, DAT files to LOGS
- Subdirectory mapping: 8BDATA→8BLOG, DSCDATA→DSCLOG, etc.
- Result: Database import now functional

## VPN System Completion (Part 2)

**Peaceful Spirit VPN Setup:**
- Created Setup-PeacefulSpiritVPN.ps1 (ready-to-run with credentials)
- Created Create-PeacefulSpiritVPN.ps1 (interactive with parameters)
- Created VPN_QUICK_SETUP.md (comprehensive 350+ line guide)

**Configuration:**
- Server: 98.190.129.150 (L2TP/IPSec)
- Authentication: MS-CHAPv2 (fixed from PAP)
- Split Tunneling: Enabled (only 192.168.0.0/24 uses VPN)
- Network: UniFi router at CC location
- DNS: 192.168.0.2, Gateway: 192.168.0.10

**Authentication Fix:**
- Error: PAP doesn't support Required encryption with L2TP/IPSec
- Solution: Changed to MS-CHAPv2 authentication
- Updated all scripts and documentation

## Credentials Documented (UNREDACTED)

**Complete credentials for:**
- Peaceful Spirit VPN (PSK, username, password, network config)
- AD2 (192.168.0.6) - C$ admin share connection method
- D2TESTNAS (192.168.0.9) - SMB1 proxy
- Jupiter (172.16.3.20) - Gitea server
- GuruRMM (172.16.3.30) - Database and API
- Gitea SSH key (needs to be added to server)

## Documentation Updates

**Files Modified:**
- session-logs/2026-01-19-session.md: Complete rewrite with both DOS and VPN work
- credentials.md: Added VPN section with network topology
- VPN_QUICK_SETUP.md: Added split tunneling section, updated examples

**Session Statistics:**
- Duration: ~5 hours (DOS + VPN work)
- Files Created: 8 files
- Files Modified: 5 files
- Lines of Code: ~1,200 lines
- Credentials Documented: 10 systems/services
- Issues Resolved: 6 issues (4 DOS, 2 VPN)

## Technical Details Documented

**DOS 6.22 Limitations:**
- Never use: %COMPUTERNAME%, IF /I, %ERRORLEVEL%, FOR /F, &&, ||
- Always use: IF ERRORLEVEL n, GOTO labels, simple FOR loops

**VPN Authentication:**
- L2TP/IPSec with PSK requires MS-CHAPv2, not PAP
- Required encryption only works with MS-CHAPv2 or EAP

**Split Tunneling:**
- Only traffic to 192.168.0.0/24 routes through VPN
- All other traffic uses local internet connection
- Configured via Add-VpnConnectionRoute

**CTONW Data Routing:**
- ProdSW: Software distribution (bidirectional)
- LOGS: Test data for database import (unidirectional upload)
- Separation critical for database import workflow

## Sync Workflow Documented

**AD2 → NAS (Software): PUSH**
- Admin deposits in C:\Shares\test\COMMON\ProdSW\
- Sync-FromNAS.ps1 runs every 15 minutes
- PSCP copies to /data/test/COMMON/ProdSW/
- DOS machines download via NWTOC from T:\COMMON\ProdSW\

**NAS → AD2 (Test Data): PULL**
- DOS machines write to T:\TS-XX\LOGS\
- Sync pulls to C:\Shares\test\TS-XX\LOGS\
- Files deleted from NAS after copy
- DAT files auto-imported to database

**Root Files: PUSH**
- UPDATE.BAT and DEPLOY.BAT sync to /data/test/ root
- Available at T:\UPDATE.BAT and T:\DEPLOY.BAT

## Pending Tasks

**Immediate:**
- DOS and VPN work complete ✅

**Short-term:**
- Add SSH key to Gitea for /sync command
- Deploy VPN to client machines
- DOS pilot deployment to 2-3 machines

## Context Recovery

Session log now contains complete context for:
- AD2 connection methods (C$ admin share works)
- CTONW test data routing (v1.2 separates ProdSW/LOGS)
- VPN authentication (MS-CHAPv2, not PAP)
- Split tunneling configuration
- All credentials unredacted
