feat: #3626850 Add header, footer, page layout and state options to the sign-in screens (!10) · Merge requests · project / uikit_admin

Stacked on the merge request of #3626849: merge that one first.

Show the status messages in the card: a wrong password, a sent link and an expired link now say what happened.
Add the options: header and footer of the site, logo (site, theme or none), an image with its credit, a help line and a Display Builder page layout, with schema, choices, length limits and a post update.
Give each screen its own class (login, register, password, reset, logout, denied) and add the log out confirmation to the sign-in routes.
Show an access denied page on a sign-in path as a sign-in screen, never with the rail; say that accounts are created by an administrator when registration is closed.
Redesign the component: 26rem card, 16px fields, 44px targets, logical properties, 100dvh, a fixed dark brand panel, a short brand row on phones, a three-line clamp for long names, a logo tile, an image under a dark layer, and no empty links row.
Style the View Password button as a 44px button inside the field with an icon in the text color, in both directions, and the password strength meter with state colors.
Log in form: no autofocus, no help text, a "Forgot your password?" link under the password; the reset form says "Send reset link" and returns to the log in screen.
Make the error border and the required marker readable in the dark mode.
Describe every prop and slot of the component, add a story for each layout, and a UI Skins token for the logo tile.
Tests: new 01-04-02-sign-in-options.feature and 01-04-03-sign-in-states.feature.
