Add RMF icon contract coverage

[cursor]

Asana Task/Github Issue: N/A

Description

Adds focused unit coverage for the New Tab RMF icon contract after recent RMF pictogram additions.

• Risky behavior now covered: RMF icon names accepted from native data must stay in sync across the JSON schema enum, generated RMFIcon TypeScript union, mock fixtures/examples, and bundled *-96.svg assets.
• Test files added/updated: special-pages/unit-test/rmf-icons.spec.mjs.
• Why these tests materially reduce regression risk: missing enum/type/asset updates for a new RMF pictogram can silently break native-delivered messages or render broken icons; this test fails deterministically at unit-test time before integration/screenshot coverage is needed.

Testing Steps

• npm run test-unit -w special-pages
• npx prettier --check "special-pages/unit-test/rmf-icons.spec.mjs" && npx eslint "special-pages/unit-test/rmf-icons.spec.mjs"
