Email verification template missing in Docker container causes crash #814
Description
When running the application in the official Docker container, the email verification template HTML is not present inside the image. This causes the program to crash whenever it attempts to send a verification email.
Proposed solutions:
- Bundle the missing template HTML files into the Docker image so email sending does not fail.
- Allow configuring the path of email templates via environment variables or application configuration, so users can mount custom templates into the container if desired.
