fix(security): override @xmldom/xmldom to ^0.8.13

Resolves 4 HIGH CVE in the xmldom transitive dep chain (Expo CLI + xcode/plist).
Not runtime-exploitable in APK (build-time deps only) but cleaned for audit hygiene.

- GHSA-2v35-w6hq-6mfw (DoS — uncontrolled recursion in XML serialization)
- GHSA-f6ww-3ggp-fr8h (XML injection via DOCTYPE serialization)
- GHSA-x6wf-f3px-wcqx (XML injection via processing instruction serialization)
- GHSA-j759-j44w-7fr8 (XML injection via comment serialization)
