Closes Issue

closes #20

Changes Made

• Added a public POST /api/waitlist endpoint that accepts an email and returns the same success response for new and duplicate addresses, so it can't be used to enumerate subscribers
• Added WaitlistService to trim, lowercase and validate emails (length and format) before they reach the database
• Added WaitlistRepository that calls a join_waitlist Postgres function
• Added a db-migrate migration (up and down) that creates the waitlist table with RLS enabled and revokes direct table access from app_public. A SECURITY DEFINER function join_waitlist handles inserts with ON CONFLICT DO NOTHING, and only app_public can execute it
• Added joinWaitlist client helper and wired it into WaitlistModal
• Allowed /api/waitlist through the coming-soon proxy so it works for signed-out visitors
• Added a React Email confirmation template, sent only for newly added emails. Attached is the template I made w AI.

Additional Notes/Screenshots/Videos (Optional)

• Run the migration before testing: npm run migrate (up). Rolling back with down drops the waitlist table and its data
• The public role has no direct access to the table. It can only call join_waitlist
