feat: Complete ISO build system with security features

Major updates for production-ready ISO:

1. **Debian Version**:
   - Updated to Debian 13.3.0 stable (released)
   - No longer using testing/sid
   - Using debian:stable Docker image

2. **Password Complexity Enforcement**:
   - Added libpam-pwquality and libpwquality packages
   - Password complexity enforced during install via PAM
   - Configured in security-config.sh:
     * Minimum 12 characters
     * Mixed case required
     * At least one digit
     * At least one special character
     * 3 character classes required
   - Preseed enforces password checks during installer

3. **Auto-Lock After 1 Minute**:
   - Added xautolock and xscreensaver packages
   - Configured in .xinitrc for auto-lock after 1 minute idle
   - Uses xscreensaver-command -lock for screen locking

4. **USB Drive Mounting**:
   - Added udisks2, gvfs-backends, gvfs-fuse packages
   - Created polkit rules for USB mounting
   - User added to plugdev and cdrom groups
   - USB drives mountable via file manager

5. **WiFi and Bluetooth Disabling**:
   - Created config/disable-wifi-bt.sh script
   - Blacklists all WiFi kernel modules
   - Blacklists all Bluetooth kernel modules
   - Masks bluetooth service
   - Removes bluez packages

6. **First-Boot Verification**:
   - Created scripts/verify-system.sh
   - Created config/football-first-boot.service
   - Verifies all functional requirements
   - Runs once on first boot
   - Prevents re-running via status file

7. **ISO Build System**:
   - Updated to use Debian 13.3.0 stable ISO
   - Scripts and config baked into ISO
   - Docker-based build process
   - Corrected ISO filename throughout

8. **Preseed Configuration**:
   - Manual user creation (not automated)
   - Manual password prompts (enforced via PAM)
   - Late_command applies all security configs
   - Copies verification script to target
   - Enables first-boot verification service

Files Added:
- config/disable-wifi-bt.sh (WiFi/BT disabling)
- config/security-config.sh (password complexity, auto-lock, USB mounting)
- config/football-first-boot.service (first-boot verification systemd service)
- scripts/verify-system.sh (comprehensive verification script)

Files Updated:
- config/preseed.cfg (password enforcement, security packages, late_command)
- scripts/build-iso.sh (Debian 13.3.0, correct filenames)
- docs/FUNCTIONAL-REQUIREMENTS.md (verification strategy)
- AGENTS.md (documentation references)
- README.md (documentation references)

All requirements from this session implemented:
✓ Password complexity enforced during install
✓ Auto-lock after 1 minute idle
✓ USB drive mounting enabled
✓ WiFi/Bluetooth disabled
✓ First-boot verification
✓ Scripts baked into ISO (no internet needed)
✓ All packages in ISO
✓ Debian 13.3.0 stable
