2nd email address field

🔍 Problem Statement

Customer accounts in Pelcro only support a single email address. Organisations that need to associate a secondary email (e.g. billing vs. access, or personal vs. corporate) have no way to store it without using workarounds like metadata fields.

💡 User Story

As a Pelcro admin, I want to add a second email address to a customer account, so that I can store separate billing and access emails without relying on metadata workarounds.

🎯 Definition of Done (DoD)

A feature is done when:

✔️ Given a customer profile, when an admin adds or edits a second email address, then both the primary and secondary email are stored, visible in the dashboard, and available via the API.
