Replaces the plain-text invite email with a standalone react-email
template (apps/broker/src/emails/mesh-invitation.tsx) using
@react-email/components + Tailwind. Rendered on demand in
handleCliMeshInvite and sent as both HtmlBody and TextBody via
Postmark (or html+text via Resend).
Self-contained — no dependency on @turbostarter/email, i18n, or ui
packages. Adds react, react-dom, @react-email/components, @react-email/render
to broker deps. Enables tsconfig jsx: react-jsx and .tsx includes.
