feat(02-02): install nodemailer and create contact mailer + server action

- Add nodemailer@^7.0.7 and @types/nodemailer (v7 required by next-auth peer dep)
- Create src/lib/contact-mailer.ts: Nodemailer SMTP transporter + sendContactEmail()
- Create src/lib/contact-action.ts: Server Action with Zod validation, honeypot check
- SMTP credentials read from CONTACT_EMAIL_USER/PASS/SMTP_HOST/PORT env vars
- Add CONTACT_* placeholder vars to .env.local (gitignored, for local setup docs)
