fix: Move email-validator to runtime dependencies (#51)

* fix: Move email-validator to runtime dependencies

The generated types use Pydantic's EmailStr which requires email-validator
at runtime. Previously it was only in dev dependencies, causing the CLI to
fail with "ModuleNotFoundError: No module named 'email_validator'".

* test: Add CLI import test to catch missing runtime dependencies

Added test_cli_imports_successfully to verify that the CLI can import
all required dependencies, specifically including types that use EmailStr
which requires email_validator. This test would have caught the bug where
email_validator was only in dev dependencies.

The test imports Contact from brand_manifest which uses EmailStr, triggering
Pydantic's validation that requires email_validator to be installed.
