jared ac05b212b2 Fix performAdvancedSearch ReferenceError, settings save, sort reset, notifications 500, CSP
DashboardView.php: wrap performAdvancedSearch in a closure so it is
resolved at event-fire time rather than listener-registration time
(advanced-search.js loads later via pageScripts so the bare identifier
reference caused ReferenceError).

DashboardView.php: reset sort URL to page=1 so sorting all pages
instead of staying on the current page.

dashboard.js: add missing save-settings and close-settings cases to
the click delegation handler (were removed in a prior session under
the assumption they were in dashboard.js, but they were not).

notifications.php: replace JSON_EXTRACT-based comment join (not
universally supported) with a two-step PHP filter: fetch owner/watcher
ticket IDs first, then filter raw comment rows in PHP. Also fix the
status change LIKE pattern to match the actual logTicketUpdate format
{"status": {"from": ..., "to": ...}}.

SecurityHeadersMiddleware.php: add https://cdn.jsdelivr.net to
connect-src so Chart.js source maps load without CSP violations.
