fix: connect EmailService to contact form handler

The contact form was logging submissions but never actually sending emails.
This commit:
- Adds EmailService field to CVHandler
- Initializes EmailService in main.go with SMTP config
- Calls SendContactForm in HandleContact handler
- Updates all test files to pass nil for emailService parameter
