Patterns on the covers, a search box that is simply there, roomier margin notes

Four small things about the shape of the app.

Covers can be patterns as well as colours — ruled paper, graph paper,
pinstripe, bands, dots, cross-hatch, linen, washes, a ledger — drawn
entirely with CSS gradient layers. No image files, nothing to upload,
crisp at any size, and offline like everything else. A cover is stored as
an index into that list, so the new ones are appended and never inserted:
renumbering would silently repaint every notebook anyone already has.

Two things the patterns taught. One idea per cover: two crossed diagonals
meant as a chevron came out as noisy plaid at the size a cover is
actually read, and were replaced with plain bands. And the grid has to
scroll — with 27 covers the dialog ran past the bottom of a laptop screen
and took the Create button with it, which a check now holds at 1440x800.

The search box in a notebook is simply there now, and the button that
used to open it is gone. A magnifying glass cost a click and having to
remember that searching was possible at all; a search box is one line and
says for itself what it does.

Margin notes went from 208x74 to 288x112 — from three short lines to
about five. Three lines is a caption, not a remark on a passage, and the
space beside the page was sitting mostly empty.

And the notebook edit dialog was still part German, and would not say
what the server's default number of versions actually is. It names it
now, read from the server rather than written into the interface: it is
set with MAX_VERSIONS_PER_NOTE, and a hardcoded "50" would quietly start
lying the day that changed.

+## Unreleased

+**Added**
+- **Patterned notebook covers** — ruled paper, graph paper, pinstripe, bands,
+  dots, cross-hatch, linen, washes, a ledger. Drawn entirely in CSS: no image
+  files, nothing to upload, crisp at any size, and they work offline like
+  everything else. Existing notebooks keep exactly the cover they had; the new
+  ones are appended, never inserted.

+**Changed**
+- **The search box in a notebook is simply there**, and the button that used to
+  open it is gone. A magnifying glass cost a click and having to remember that
+  searching was possible; the box is one line and says for itself what it does.
+- **Margin notes are bigger** — the column went from 208px to 288px and a card
+  from three short lines to about five. Three lines is a caption, not a remark
+  on a passage, and the space beside the page was sitting mostly empty.
+- The notebook dialog's cover grid scrolls, so the dialog cannot run past the
+  bottom of a laptop screen and take the *Create* button with it.
+
+**Fixed**
+- The notebook edit dialog was still part German — *"Versionen pro Notiz"*,
+  *"Vorgabe"* — and would not say what the server's default actually is. It now
+  names it (50), read from the server rather than written into the interface,
+  since `MAX_VERSIONS_PER_NOTE` can be changed and a hardcoded number would
+  quietly start lying.
