Move SMTP configuration retrieval from class initialization to method scope in send_email_by_smtp. This improves encapsulation and ensures the latest settings are used when sending emails.
Introduced support for MailerSend as an email provider alongside SMTP, with configuration options in settings. Added Jinja2-based multi-language email templates for verification emails, and refactored the email sending logic to use these templates and support language selection based on user country code. Updated related services and API endpoints to pass country code and handle new response formats. Added dependencies for Jinja2 and MailerSend.
format: {time:YYYY-MM-DD HH:mm:ss} [{level}] | {name} | {message}
{name} is:
- Uvicorn: log from uvicorn server (#228B22)
- Service: log from class of `app.service` (blue)
- Fetcher: log from fetchers (magenta)
- Task: log from `app.tasks` (#FFD700)
- System: log from `system_logger` (red)
- Normal: log from `log(name)` (#FFC1C1)
- Default: the module name of caller
if you are writing services or tasks, you can just call `logger.`, we will pack it with name `Service` or `Task`
if you want to print fetcher logs, system-related logs, or normal logs, use `logger = (fetcher_logger / system_logger / log)(name)`
