[CLI] Restore the "login" argument handler

[bgrgicak]

This PR restores support for login in the CLI using a login argument.

The support was previously removed in #1811.

Testing Instructions (or ideally a Blueprint)

• Run bun ./packages/playground/cli/src/cli.ts server --login
• Open Playground and see that you are logged in

@adamziel I realized my mistake with removing login support. While working on #1811 I kept running into issues with login and made an incorrect assumption that it won't work anymore with autologin.

What caused the confusion for me is that I expected the --login argument to override the Blueprint, but we don't override Blueprints in the CLI.

wordpress-playground/packages/playground/cli/src/cli.ts

Lines 209 to 220 in 236c236

	let blueprint: Blueprint | undefined;
	if (args.blueprint) {
	blueprint = args.blueprint as Blueprint;
	} else {
	blueprint = {
	preferredVersions: {
	php: args.php as SupportedPHPVersion,
	wp: args.wp,
	},
	login: args.login,
	};
	}

Should we allow the wp, php, and login arguments to override Blueprints?
We did that recently on the Website with query arguments and Blueprints, so it should make the experience more consistent.

Thank you! a --debug flag that doesn't cover the entire lifecycle of the app seems confusing to me. What do you think about either renameing it to --debug-boot or making it work after the boot?

[bgrgicak]

I will add request debugging. Here is an issue to track it #1988

Potentially – this is a nice moment to explore reusing the same code paths for resolving the Blueprint in the web app and in the CLI. Would doing that be useful? If yes, what would be the most effective way to do it?

Thanks! I will leave it as is for now, but if it comes up in the future we can take a look at it.

We already have an open issue to allow the wp, php arguments to override Blueprints.
