Make the page transition configurable, add crossfade/slide/reveal

The cube view-transition block moves out of pagerite.css into transition
designs (pagerite/themes/{name}/transition.css), handled like banner
designs: served from disk at /_themes/..., injected by the backend as
#pagerite-transition after the banner sheet, and picked site-wide in the
site settings (Data.transition, default cube; GET/PUT /_api/settings
carry transition + the designs found on disk). The site editor swaps the
sheet in place on change; the dev-mode order fixup knows the new id.

Designs: cube (unchanged), crossfade (all navigations), slide (sideways,
both pages moving together) and reveal (clip-path wipe over the
stationary old page) — the latter two mirrored on history-back and
crossfading within a section like cube.

Also compress the site settings form into a two-column grid: site name +
favicon on one row, theme + transition on the next.

`Data.theme` is the active theme name (empty = none/base only); themes are folders in `pagerite/themes/{name}` containing `theme.css` and/or `banner.css` (+ `banner.svg` artwork and any extra assets the CSS references, like summer's `grass.svg`), served by the backend at `/_themes/{name}/...` — read from disk per request (etag by mtime), never built, so on-disk edits show on the next page load even in prod. The theme selector and banner-design selector enumerate these folders via `GET /_api/settings`.
`Data.transition` is the page-transition design name (default `cube`): a theme folder shipping `transition.css`, injected as `#pagerite-transition` on every page and selected in the site editor (the selector enumerates `transition.css` folders via `GET /_api/settings`). See `docs/themes-and-assets.md`.
`Data.custom_css` is raw trusted CSS injected inline in every page `<head>` (id `pagerite-user`) and swapped during fetch-navigation; editable in the site editor. Font picks (heading/body/brand) in the site editor are stored as plain `:root` rows in `custom_css` (`--font-body: var(--font-source-sans);` format — parsed out and rewritten on change, the `:root` block added/removed as needed), referencing the per-family variables (`--font-source-sans` etc.) from `pagerite.css`; the base stylesheet's `--font-brand` defaults to `var(--font-heading)`.
`Data.favicon` names a file in the content-addressed store (on disk under `<hostname>/files/`), uploaded/cleared in the site editor via `PUT`/`DELETE /_api/settings/favicon`; when set it is linked as `<link rel="icon">` on every page, otherwise browsers fall back to the build's `/favicon.ico` by convention.
