Brandon Schneider 7eda71868a refactor(rds): consolidate 14 psycopg2 connect patterns into shared rds_connect module
Creates 4-Infrastructure/shim/rds_connect.py with a single connect_rds()
function that resolves connection parameters in priority order:
  1. explicit kwargs
  2. DATABASE_URL env var (postgres://user:pass@host:port/dbname?sslmode=...)
  3. individual RDS_* env vars (RDS_HOST, RDS_PORT, RDS_USER, etc.)
  4. built-in defaults

Auth resolution (when password is empty or RDS_IAM=1):
  1. RDS_IAM_TOKEN env var (pre-computed)
  2. boto3 SDK generate_db_auth_token (preferred)
  3. subprocess aws rds generate-db-auth-token (fallback)
  4. RDS_PASSWORD env var (non-IAM)

Replaces 8 connection pattern variants across 14 active shims:
  - subprocess + RDS_IAM_TOKEN fallback: pist_trace_classify_mcp, joint_classifier,
    pist_prove_and_classify, ingest_57_flexures
  - boto3 SDK: ene_wiki_body_reingest, ene_migrate_and_tag, dataset_ingest_rds
  - subprocess + RDS_PASSWORD: batch_embed_artifacts, sync_wiki_to_rds, seed_flexure_dataset
  - RDS_IAM_AUTH: pist_classify
  - bashrc parsed: credential_loader

v1.4a benchmark confirmed at 100% after refactor.
