step 5 (continued): prune stale root files, drop frontend split

Delete Dockerfile.frontend and docker-entrypoint-fe.sh (single-image
decision per ROADMAP). Remove gutted /chat, /notes, /projects routes
from nginx.conf. Fix Chat Switchboard branding in entrypoint and
.env.example. Update DB names to switchboard_core, remove dead
Extraction config.
