chore(SEC-16541): security upgrades for react-native-webview

[casper-phantom]

Resolves SEC-16541

Caution

Critical risk: This change addresses a critical security advisory in a transitive parser dependency; rollback restores the vulnerable version.

Summary

• Resolve GHSA-m7jm-9gc2-mpf2 by pinning every transitive fast-xml-parser consumer to the patched 4.5.x line.
• Regenerate the Yarn lockfile so the repository resolves fast-xml-parser 4.5.6 instead of vulnerable 4.3.5.
• Refresh the existing advisory PR onto current master rather than opening a duplicate.

Agent provenance

• Implementation and validation: Oz — not exposed by host / not exposed by host

Verification

• yarn install --frozen-lockfile --non-interactive
• yarn lint
• yarn build
• yarn list --pattern fast-xml-parser → fast-xml-parser@4.5.6

Closes SEC-16541
Supersedes SEC-11595
