📝 Walkthrough

Walkthrough

Adds admin email storage and retrieval, CLI support to set/display emails, an SMTP2GO-backed EmailService, and async notification of admins after record creation; includes DB migrations for adding/dropping the email column and index.

Changes

Cohort / File(s)	Summary
Database Schema src/sql/007_add_admin_email.up.sql, src/sql/007_add_admin_email.down.sql	Add email VARCHAR(255) to admin_orcids and create idx_admin_orcids_email; down migration drops the index and column.
Repository Layer src/cmd/repositories.go, src/category_repository.go	Admin struct gains Email field. AdminRepository.Add signature extended to accept email. New interface method GetAllEmails(ctx) added and implemented in PostgresAdminRepository; GetAll/Add now select/insert email.
CLI Updates src/cmd/cli.go	admin add accepts optional email (add <orcid> [email]); addAdmin signature extended; admin listing shows Email (displays "(not set)" when empty); seed path updated to pass email.
Email Service src/email.go	New EmailService with NewEmailService() and SendNewRecordNotification(...); builds text/HTML bodies and posts SMTP2GORequest to SMTP2GO API with timeout and gating when disabled or no recipients.
Record Handler Integration src/record_handler.go	RecordHandler adds emailService (initialized via NewEmailService()); after successful record create/S3 upload spawns goroutine that calls GetAllEmails() and SendNewRecordNotification, logging any errors.
Dev Environment docker-compose-dev.yml	Adds environment variables SMTP2GO_API_KEY, EMAIL_FROM_ADDRESS, and EMAIL_FROM_NAME to dev service.

Poem

🐇 I hopped through rows of ORCIDs bright,
Poked a new column into the night,
A fluttering SMTP2GO song sent,
Admin mailboxes cheerfully went,
— Signed, a rabbit, with a tiny byte ✨📧

why is this function repeated from cmd/repositories.go ? Can't we share such code between web and cli?
