OCPBUGS-98765: Bump linkify-it to 5.0.2 to fix CVE-2026-48801

[prabhapa]

CVE-2026-48801: linkify-it ReDoS vulnerability

Bumps the transitive dependency linkify-it from 2.1.0 to 5.0.2 via yarn resolutions to address CVE-2026-48801 (CVSS 7.5 Moderate).

Vulnerability

linkify-it < 5.0.1 has O(N²) algorithmic complexity in LinkifyIt.prototype.match, enabling ReDoS (Regular Expression Denial of Service) via crafted input with many fuzzy links or emails (CWE-1333).

Changes

• Added "linkify-it": "^5.0.1" to frontend/package.json resolutions block to override the transitive dependency pinned by react-linkify@0.2.2
• linkify-it: 2.1.0 → 5.0.2
• uc.micro (child dep): 1.0.6 → 2.1.0

Validation

• Jest unit tests: 9/9 passed
• Webpack production build: succeeded (127s, zero linkify-related warnings)
• Runtime compatibility verified: react-linkify@0.2.2 works correctly with linkify-it 5.x API
