Changed all COUNT(*) to COUNT(*) as count and access via ['count'].
Fixes: KeyError: 0 on cur.fetchone()[0]

All conn.cursor() calls replaced with get_cursor(conn) to enable

This fixes KeyError when accessing PostgreSQL query results.
Fixes: 'tuple' object has no attribute '__getitem__' with string keys

Added meas_id as nullable UUID column for backward compatibility.

- Remove postgresql-client installation (causes 150s+ hangs due to network)
- Add db_init.py: Pure Python PostgreSQL checks using psycopg2-binary
- Simplify startup.sh: Call Python script instead of psql commands
- Build should now complete in <30s instead of hanging
This fixes the deployment timeout issue by avoiding APT network problems entirely.
