mailgun integration + templates

[MrImmortal09]

Context

Magic link sign-in, event reminders, recovery notifications, and onboarding all need email delivery. Use mailgun stmp/api (cheap, developer-friendly, good templating).

Check how iiitl/student-hub mailing works and apply same here as well

Acceptance criteria

• Mailgun API key in env.example
• lib/email/ module with typed send functions
• EmailLog table records every send for debugging

Depends on #1.
