fix(security): Implement Phase 1 critical security fixes

CORS: - Restrict CORS to DASHBOARD_URL environment variable - Default to production dashboard domain Authentication: - Add AuthUser requirement to all agent management endpoints - Add AuthUser requirement to all command endpoints - Add AuthUser requirement to all metrics endpoints - Add audit logging for command execution (user_id tracked) Agent Security: - Replace Unicode characters with ASCII markers [OK]/[ERROR]/[WARNING] - Add certificate pinning for update downloads (allowlist domains) - Fix insecure temp file creation (use /var/run/gururmm with 0700 perms) - Fix rollback script backgrounding (use setsid instead of literal &) Dashboard Security: - Move token storage from localStorage to sessionStorage - Add proper TypeScript types (remove 'any' from error handlers) - Centralize token management functions Legacy Agent: - Add -AllowInsecureTLS parameter (opt-in required) - Add Windows Event Log audit trail when insecure mode used - Update documentation with security warnings Closes: Phase 1 items in issue #1 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
fix: DOS 6.22 compatibility - remove 2>NUL, add XCOPY /I flag

 .SYNOPSIS
-    GuruRMM Legacy Agent - PowerShell-based agent for Windows Server 2008 R2 and older systems
+    GuruRMM Legacy Agent for Windows Server 2008 R2 and older systems.

 .DESCRIPTION
-    Lightweight RMM agent that:
-    - Registers with GuruRMM server using site code
-    - Reports system information
-    - Executes remote scripts/commands
-    - Monitors system health
+    This PowerShell-based agent is designed for legacy Windows systems that cannot
+    run the modern Rust-based GuruRMM agent. It provides basic RMM functionality
+    including registration, heartbeat, system info collection, and remote command
+    execution.
+
+    IMPORTANT: This agent is intended for legacy systems only. For Windows 10/
+    Server 2016 and newer, use the native Rust agent instead.
+
+.PARAMETER ConfigPath
+    Path to the agent configuration file. Default: $env:ProgramData\GuruRMM\agent.json
+
+.PARAMETER ServerUrl
+    The URL of the GuruRMM server (e.g., https://rmm.example.com)
+
+.PARAMETER SiteCode
+    The site code for agent registration (e.g., ACME-CORP-1234)
+
+.PARAMETER AllowInsecureTLS
+    [SECURITY RISK] Disables SSL/TLS certificate validation. Required ONLY for
+    systems with self-signed certificates or broken certificate chains.
+
+    WARNING: This flag makes the connection vulnerable to man-in-the-middle
+    attacks. Only use on isolated networks or when absolutely necessary.
+
+    This flag must be explicitly provided - certificate validation is enabled
+    by default.
+
+.PARAMETER Register
+    Register this agent with the server.
+
+.EXAMPLE
+    # Secure installation (recommended)
+    .\GuruRMM-Agent.ps1 -Register -ServerUrl "https://rmm.example.com" -SiteCode "ACME-CORP-1234"
+
+.EXAMPLE
+    # Insecure installation (legacy systems with self-signed certs ONLY)
+    .\GuruRMM-Agent.ps1 -Register -ServerUrl "https://rmm.example.com" -SiteCode "ACME-CORP-1234" -AllowInsecureTLS
+
+.EXAMPLE
+    # Run the agent
+    .\GuruRMM-Agent.ps1
