fix(frontend): Sanitize DOM rendering to prevent XSS via innerHTML

Replace unsafe innerHTML template literals with document.createElement()
and textContent for all user-conrolled data fields in index.html.

Event cards and modal details previously interpolated API responses
(event.name, event.title, player.fname, staff.role, etc.) directly into
innerHTML without escaping, allowing stored XSS if upstream MyIce data
is malicious (CWE-79 / vuln-0002).

All dynamic text now flows through textContent or createTextNode(),
while static HTML structures (SVG icons, strong labels) remain safe
hardcoded innerHTML assignments.
