feat: console command to send test email

[mechanarchy]

This PR will close #3128, it will also close #3890. It adds the monica:test-email command, to test whether email delivery is working. Prior to this, I had to repeatedly attempt to send password reset emails for testing (as did user @theexplosivegroup).

The PR contains hard-coded strings: personally, I'm not sure there is value in translating them because they are strictly for testing purposes, and the content is largely irrelevant (you only care if you get the email).

Use as follows:

php artisan monica:test-email --email=my_email@provider.com

If no email is provided as an argument, the command will prompt you for one, but it does not verify that the email belongs to any registered user.

@mechanarchy is it possible you write a test for the command?

Hi!
I think that's a great idea.

It just missed some unit tests.

[mechanarchy]

Sorry it took me a while - I haven't done a lot of PHP. But there are some basic tests now! Thanks for the approval :)

Really great job @mechanarchy ! Thanks a lot

Hi asbiin, I tried converting the string-variable concatenation into an interpolation like you suggested, but Psalm tests fails due to PossiblyInvalidCast non-empty-array<array-key, mixed> cannot be cast to string (see https://psalm.dev/190).

I looked at another command with a similar signature, and it is using string concatenation as well:

monica/app/Console/Commands/SetupProduction.php

Lines 63 to 69 in 5bf2626

	$email = $this->option('email');
	$password = $this->option('password');
	if (! empty($email) && ! empty($password)) {
	Account::createDefault('John', 'Doe', $email, $password);
	$this->info('| You can now sign in to your account:');
	$this->line('| username: '.$email);

I couldn't find a way around this after some searching and trial and error, so I think it may have to stay as concatenation unless you know a solution.

That's a great job, thank you @mechanarchy
