refactor(log): refactor the whole project

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)`
