A native feed list and item list (#3)

The lists are native now, and the page is a button in the toolbar: it is
still where signing in happens, and it is still the whole of settings, the
admin page, the directory and OPML, which were never going to be rewritten.

LibraryStore holds a page of items and asks for the next, because the
sorting, filtering and searching are the server's work and ten thousand
items have no business being in memory to be sorted here. Read and pinned
are set locally and sent after, as the page's readWrites map does and for
the same reason: a list asked for before the write lands answers with the
old state, which put the dot back on an item just read.

The interface follows the account's light or dark rather than the phone's,
and defaults to dark when nobody has chosen, because that is what ipx's own
theme.ts does. Following the system instead put a light list in front of a
dark page. preferredColorScheme was not enough on its own -- inside a
hosting controller it did not reach the hierarchy -- so the style is
overridden on the controller, which also carries to the page presented over
it.

The sidebar had to be broken into sub-views: the whole list in one
expression was more than the type checker would work through, and it said
so rather than compiling it.

Tested against the real library, 135 feeds and eleven thousand items, and
the playback test now drives the native row rather than the page's button.
Thirteen pass.
