Submitted frontend PR: stakwork/sphinx-tribes-frontend#1604

What changed:

• Converts Loom /share/{id} URLs into /embed/{id} before rendering the modal iframe
• Keeps query params intact
• Replaces raw dangerouslySetInnerHTML iframe injection with a React iframe
• Adds regression coverage for share-link rendering

Validation:

• REACT_APP_IS_TEST=true NODE_ENV=test node node_modules/jest/bin/jest.js --runTestsByPath src/people/utils/__tests__/LoomViewerRecorder.test.tsx --runInBand --no-coverage --silent --transformIgnorePatterns "./svg/"
• git diff --check
