Rework forms, statistics, design and the sidebar foot in 1.15.0

Forms are an editor now: one card per field with add and remove, the
technical name derived from the label, options only for a choice, and a
new "Aussehen" section with a button label and four colours (field border
and background, button and button text) that travel to the page as one
rule per form inside the hashed style block. A live preview draws the
form with the site's default button and names the text contrast.

Statistics open with six figures (views against the same span before,
average per day, busiest day, pages, referred views, missing addresses),
a chart with grid lines and a title per bar, a weekday chart and ranked
lists with share bars. The design screen shows the palette as colour
cards with seven ready-made palettes, picks the base colours from the
palette, previews every font in itself and the typography as a sample.
The sidebar ends in an account card with role and a logout icon.
