chore: clean absolute paths, curasoft refs, secrets from history

- bin/chats/: env-based paths, no /mnt/ /home/ hardcodes
- bin/edelweiss-pilot: remove curasoft, use DOCS_BASE env var
- bin/facts/crm: use KNOWLEDGE_MESH_SEED env var
- compose.edelweiss.yml: remove curasoft volumes, use DOCS_BASE
- docs/chat-import-plan.md: link to Gitea issue, no secrets
- bin/seed-edelweiss-facts.py: removed (curasoft-only)
