Remove the desktop wallpaper

The desktop no longer shows a wallpaper. It shows the page's plain
background color: white, or #1e1e1e in dark mode. The sign-in dialogs
and account picker that opened over the wallpaper now open over that
color too.

This removes the default wallpaper image and its credit, its preload in
both page shells, the "Set as Desktop Background" item on images'
right-click menu, the GUI's set_desktop_background and
refresh_desktop_background, and the set_as_background i18n key.
Desktop icon labels were white with a shadow to read on the wallpaper;
they now use the same gray as labels inside windows, and a light gray
in dark mode.

The backend drops POST /set-desktop-bg, and /whoami no longer returns
desktop_bg_url, desktop_bg_color or desktop_bg_fit. The user table's
desktop_bg_* columns stay; dropping them needs a migration.

 what was refused, through a consent dialog when the click has expired or the
 tab is blocked, and `requestUpgrade()` resolves `{ upgraded: false }`.
 
+## Top-up
+
+`GET /embed/top-up` is the deployment's top-up dialog, where a user with a plan
+buys add-on credit, served and framed like the upgrade: a transparent GUI page
+covering the host with no box or close button, allowing `payment` and
+`otp-credentials`, with Escape left to the dialog. Its fragment names `user`.
+
+puter.js frames it for the **Add credits** item of `<puter-user-menu>`, which
+shows only when whoami reports `subscribed: true` and no `team` paying for the
+account. On a page that can't frame the GUI, the item opens the dashboard with
+`?topup=` in a new tab instead.
+
+The GUI reports `unavailable` unless its session belongs to `user`, the account
+has no verification or password change waiting, and the deployment defines
+`window.UITopUp` with `UITopUp.embeddable === true`. Otherwise it runs:
+
+```js
+new UITopUp({ onClose }).open();
+```
+
+`open()` resolves once the dialog has loaded the account and shows what it can
+buy, and `onClose({ toppedUp })` must run exactly once, when the dialog closes
+or when it declines to open for the account. The GUI then posts `{ msg: 'puterPopupFrame', state: 'closed', toppedUp }`
+and the page removes the frame. When the frame can't show the top-up, puter.js
+opens the dashboard's top-up in a new tab, as it does the upgrade.
+
+While the top-up shows, a call refused for funds still rejects but opens no
+usage limit dialog over it, and `requestUpgrade()` frames nothing over it: it
+resolves `{ upgraded: false }` once the top-up closes.

+## Custom domains
+
+`GET /embed/attach-custom-domain` is the custom domain dialog of
+`puter.hosting.attach()`, the popup at `/action/attach-custom-domain`, served
+like the upgrade: the GUI shell with the same framing rules, redirects and
+`no-store`, run only when framed by an allowed page. puter.js frames it on a
+signed-in first-party page (the same pages as the pickers).
+
+The frame covers the page with no box or close button, over a transparent GUI
+page, so the dialog floats over the host with its own scrim as it does on the
+desktop. The frame allows `clipboard-write`, for the dialog's copy buttons, as
+well as `otp-credentials`. Escape on the page is left to the dialog, which
+doesn't close while a request is in flight. Its fragment names `user` (the
+page's signed-in user), `subdomain` (the site to attach a domain to) and
+`msg_id`.
+
+The GUI reports `unavailable` unless its session belongs to `user` and the
+account has no verification or password change waiting. It then runs the
+popup's action unchanged, with the framing page as the requester the dialog
+names: it posts `ready` once the dialog is on the page, answers
+`{ msg: 'customDomainAttached', domain, original_msg_id }` once the dialog has
+closed and its exit has played, and then posts `closed`. `domain` is the domain the user chose, or
+null. `attach()` resolves it. A frame that closes without an answer, or a
+loading scrim the user dismisses, resolves null.
+
+A call made while the frame shows resolves null without replacing it, as a
+second call does on the desktop. A frame that is refused, never ready, or
+`unavailable` falls back to the popup, which can sign in, through a consent
+dialog when the click has expired.

-Chat requests accept JSON bodies up to 128 MiB (134,217,728 bytes), including `text/plain;actually=json` bodies. That covers `puter-chat-completion` calls through `/drivers/call`, which `puter.ai.chat()` uses, and POSTs to `/puterai/openai/v1/*`, `/puterai/anthropic/v1/messages` and `/puterai/anthropic/v1/messages/count_tokens`. A body over 50 MiB needs a `Content-Length` header and a token in the `Authorization` or `x-api-key` header (or a session cookie); an `auth_token` inside the body isn't read until the body is, so it only works up to 50 MiB. Larger bodies, and bodies over 50 MiB for other drivers, return HTTP 413. One account can have up to 128 MiB of these large bodies in flight at once; past that, requests get `429` with `Retry-After`. A server handling too many large bodies at once returns `503` with `Retry-After`. Retry either after the given number of seconds. Other routes accept JSON bodies up to 50 MiB.

That is a token in the `Authorization` or `x-api-key` header, a session cookie, or an `auth_token` that is the first field of the body, which is where Puter.js sends it. An `auth_token` after other fields isn't read until the body is, so it only works up to 50 MiB. Larger bodies, and bodies over 50 MiB for other drivers, return HTTP 413.

A JSON body in a charset other than UTF-8 is accepted up to 1 MiB. A JSON body over 32 KiB can nest arrays and objects up to 10,000 levels deep, and deeper nesting returns HTTP 400.
