Serilog.Sinks.Email v4 renamed all configuration parameters from their
v2 names. The old names were silently ignored, so no error alert emails
were ever sent.
Parameter renames applied across all 6 appsettings.json and docker-compose:
fromEmail → from
toEmail → to
mailServer → host
networkCredential → credentials
enableSsl: true → connectionSecurity: StartTls
emailSubject → subject
outputTemplate → body
batchPostingLimit / period removed (v4 batching uses a separate overload)

The email-api service was missing its configuration file, which is required
for Serilog logging setup, database connection, and SMTP settings.
Created appsettings.json with:
- Serilog configuration for console, file, and email logging
- Database connection settings
- SMTP configuration for email sending
- Internal API key configuration
- File storage path configuration
This fixes the container crash loop caused by missing configuration.
