fix(infra): point default RDS host to neon server Tailscale IP

- Redirected the default RDS_HOST/PGHOST database connection default
  to neon-64gb (100.92.88.64) across all Python shims, shell wrappers,
  and Rust probes.
- Cleaned up local defaults in rds_connect.py, sync_wiki_to_rds.py,
  dataset_ingest_rds.py, batch_embed_artifacts.py, db.rs, cache-offload.sh,
  db-consolidate.sh, backup.sh, and ene-api-wrapper.sh.
