Add Resend email endpoint and utility

Introduce a POST /resend endpoint and backing utility to send emails via the Resend API. Adds app/api/resend/utils/send_email.py (httpx-based sender), a Pydantic EmailRequest model and handler in app/api/resend/resend.py, and imports the new send helper. Also fixes a small typo in the root data response, updates app metadata/description and bumps __version__ to 2.0.6. Note: RESEND_API_KEY must be set in the environment. Adds pydantic[email] to requirements.
