### Description

ORDER BY RANDOM() on hosts table (6.15M rows) caused full sequential scans
taking ~7.5s each, driving PostgreSQL to 459% CPU. TABLESAMPLE SYSTEM()
samples random blocks at I/O level, reducing query time to milliseconds.
Also fixes SQL injection in thearm_uzi via parameterized query.
