Pull request overview

This PR adjusts runtime configuration to reduce Gunicorn worker memory pressure (mitigating OOM SIGKILLs under load) and makes SQLite wait longer on locks to reduce “database is locked” errors during concurrent writes.

Changes:

• Configure SQLite connection options to use a 30s lock timeout (and set transaction mode to IMMEDIATE).
• Switch Gunicorn to gthread and make worker/thread/timeout settings environment-tunable, adding max-requests recycling to bound memory growth.
• Add build dependencies to support crypto-related Python packages and introduce a new Python dependency.
