S22 tech patch 1 (#21)

* Refactor administrator fetch logic in login.inc.php

Refactor administrator fetching logic to process known IPs and fingerprints _after_ fetching the administrator record.

Those were not arrays outside the fetch block.

* Revert "Refactor administrator fetch logic in login.inc.php"

This reverts commit 2d8b928.

Restores the original fetch callback pattern where known_ips and 
known_fingerprints processing happened inside the fetch block, ensuring 
they are properly treated as arrays at the time of assignment.
