Keep the footer subscribe field readable for logged-in users

[muneeb-ashraf]

Fixes #3525.

What

For logged-in users, the Jetpack Subscriptions block in the footer prefills the email field with the account email and disables it. Jetpack's inline block CSS then applies this rule:

.wp-block-jetpack-subscriptions.wp-block-jetpack-subscriptions__supports-newline form input[type="email"]:disabled {
	color: currentcolor;
	opacity: 0.5;
}

In Learn's dark footer, currentcolor is white, so the field becomes white text on a white box at half opacity. That reads as an empty grey bar with no placeholder and no visible email, which is what the issue describes.

This adds a rule in src/style/_jetpack.scss for the disabled state only. It restores the form text color and full opacity, and uses the light form background (--wp--custom--form--search--color--background) so the field still reads as not editable. The logged-out field is unchanged.

Testing

On https://learn.wordpress.org/ while logged in, I injected the compiled rule through DevTools and checked the computed styles of the footer email field:

	Text color	Opacity	Background
Before	rgb(255, 255, 255)	0.5	white at 50% over the dark footer
After	rgb(30, 30, 30)	1	rgb(246, 246, 246)

With the rule, the prefilled email is legible next to the Subscribe button. The placeholder rule that shares Jetpack's selector list still applies as before for logged-out visitors.

I ran stylelint on the file with the wporg-repo-tools config. The only error is the existing line 3, whose disable comment still uses the old max-line-length rule name. I didn't touch it here.

I didn't attach screenshots because the logged-in state shows my account email. To check after deploy, log in and look at the "Sign up for updates" field in the footer.
