Fix France THT study load + add THT network preview - #193

The France THT game grids ship the network compressed + text-encoded as network.xiidm.gz.b64 (Git-LFS-free). The Docker build decodes them, but a build/dev checkout that skipped that step left only the .gz.b64, so pypowsybl's pn.load failed with 'Unsupported file format' and studies would not load. - network_service: decode a companion network.xiidm.gz.b64 on demand in _resolve_network_file (caches the decoded .xiidm next to it, falls back to a temp dir when the grid dir is read-only). Adds backend tests. - gen_network_previews: render preview-tht.svg for the France THT grid (reads the .gz.b64 when the raw .xiidm is absent). Wire it into the landing page so France THT mode shows its network map, like the European demo does. - Update the frontend/backend tests for the new THT preview + fallback.
