## Context
Disabling MySQL/SQLite query logging via config was not durable — Technitium
re-enables disabled plugins on pod restart, causing 46 GB/day of writes to
the standalone MySQL (15M inserts to technitium.dns_logs between CronJob runs).
## This change:
The password-sync CronJob now UNINSTALLS MySQL and SQLite query log plugins
via `/api/apps/uninstall` instead of setting `enableLogging:false`. This is
permanent — the plugin files are removed from the PVC, so they can't re-enable
on restart. The CronJob checks if the plugins are present first (idempotent).
Only PostgreSQL query logging remains (90-day retention).
