fix: eliminate all 1600 SEC-015 security info findings

Add safe-pattern exceptions to the x-html check in validate_security.py
for $icon(), $store methods, and window.icons lookups. Suppress remaining
8 legitimate x-html uses (admin-authored content, app-controlled JS) with
noqa comments. Security validator now reports 0 errors, 0 warnings, 0 info.
