Apache reverse proxy for webapp, UI improvements

- Move Flask to localhost:9010, Apache serves port 9009 with static file handling and reverse proxy to fix intermittent asset loading on remote clients - Add "PXE Manager" branding beneath logo in sidebar - Increase code editor size (startnet.cmd and unattend XML) to 70vh - Add test-lab.sh for full lab VM testing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

+# test-lab.sh — Full PXE lab: server + client VMs on an isolated network
+#
+# Creates an isolated libvirt network, boots the PXE server from the
+# Proxmox installer ISO, then launches a UEFI PXE client to test the
+# full boot chain (DHCP -> TFTP -> iPXE -> boot menu).
+#
+# Usage:
+#   ./test-lab.sh /path/to/ubuntu-24.04.iso         # Launch server
+#   ./test-lab.sh --client                           # Launch PXE client
+#   ./test-lab.sh --status                           # Check if server is ready
+#   ./test-lab.sh --destroy                          # Remove everything
+#
+# Workflow:
+#   1. Run the script with the Ubuntu ISO — server VM starts installing
+#   2. Wait ~15 minutes (monitor with: sudo virsh console pxe-lab-server)
+#   3. Run --status to check if PXE services are up
+#   4. Run --client to launch a PXE client VM
+#   5. Open virt-viewer to watch the client PXE boot:
+#        virt-viewer pxe-lab-client
