feat(server): print startup banner before heavy imports load

+"""Lightweight console-script launcher for ``start_photomap``.
+
+Importing :mod:`photomap.backend.photomap_server` pulls in FastAPI, the routers
+and (transitively) CLIP/torch, which can take 10-30s. Because the console-script
+entry point has to import its target module before calling it, a banner printed
+inside ``photomap_server.main`` only appears after that whole import finishes,
+leaving the terminal silent during startup.
+
+This module deliberately imports nothing heavy at module scope so the banner is
+printed immediately, then defers the expensive import until inside ``main``.
