- New section "Netzwerk-Topologie": one diagram per site built from NetBox cable paths (traced through patch panels), layered top-down by cabling (provider > firewall/router > core > access > endpoints), barycenter ordering, "2x" for parallel links, provider circuits as clouds and devices outside the scope dashed. Labels: management IP, model, ports. - New export format "draw.io": the topology as an editable .drawio file (one page per site, symbols embedded). - 14 built-in symbols drawn with Pillow; automatic mapping from role, model and manufacturer, passive gear (patch panels, PDUs, UPS) hidden. - New TopologySymbol model (migration 0002) with list/edit/delete UI, symbol gallery, custom icon upload and a "Topologie-Symbol" button on device type and device role pages. Bump version to 0.4.0 - requires "manage.py migrate". Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
