Subject: feat(client): add edit deck modal with form validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add EditDeckModal component that allows users to edit existing decks.
The modal pre-populates with current deck values and supports updating
name and description fields with proper validation and error handling.
