Pick the site icon from the library and crop it, find legal pages by search, list newest first

- The site icon is no longer a select at the end of the company data. It has
  its own section: a button opens the media library (upload included), then
  a square is dragged, resized by its corner, a slider or +/-, and previewed
  at 180 and 32 px. The crop is stored as fractions (faviconCrop) and the
  PNGs are cut from it; faviconVersion changes the link so browsers pick up
  a new cut. Icons without a crop keep their old link.
- openMedia() takes needsAlt: false, since the icon never appears as
  content. The dialog styles moved from editor.css to media-dialog.css so
  the dialog works outside the editor.
- Privacy page and imprint are chosen with the content search, like the 404
  page. The picker can store the path instead of the id (valueKey/data-value).
- The page and post lists in the administration sort newest first; the
  subpage indentation is gone there, as it would point at the wrong parent.

Tests: 581 PHPUnit, 35 node, test:editor green (the consent step now picks
the privacy page by search). test:admin --admin-only fails only at the known
nested-interactive menu summaries.
