Checklist

Have you pulled and found the error with jc21/nginx-proxy-manager:latest docker image?
- Yes
Are you sure you're not using someone else's docker image?
- Yes
Have you searched for similar issues (both open and closed)?
- Yes

Describe the bug
When using the INITIAL_ADMIN_EMAIL environment variable with an email address with upper case characters you are not allowed to login (Invalid email or password) because it expects to find the email address with only lower case characters in the database.

Nginx Proxy Manager Version
v2.12.6

To Reproduce
Steps to reproduce the behavior:

Set environment variable INITIAL_ADMIN_EMAIL with an upper case character

      INITIAL_ADMIN_EMAIL: Admin@example.com
      INITIAL_ADMIN_PASSWORD: changeme

docker compose up
Shows: Creating a new user: Admin@example.com with password: changeme
Try to login with either admin@example.com or Admin@example.com
Result: Invalid email or password

Expected behavior
Since the rest of the application does a toLowerCase() before changing the email in the database the initial setup.js should also do a toLowerCase() on the environment variable

I've created a PR #4664
