Named layouts lived in localStorage: invisible to anyone else, gone on the
next machine, and nothing to publish from. The one server-side layout was
pf.source.default_layout -- a single anonymous blob any account could
overwrite for every account, which is a published layout with no owner.
pf.layout replaces both. A layout is named, owned, and either private or
published; published ones are listed by everyone on the forecast and
writable only by their owner or an admin, the same rule pf.log already uses
for its entries. Scope is the version, since that is the entry point, with
version_id NULL for the source-wide default a new version inherits.
Applying is never restricted -- Save is withheld on a layout that is not
yours, Save as forks it -- because the guarantee wanted is that a published
layout cannot be changed out from under people, not that it cannot be
adapted.
The toolbar's flat chip row becomes one Layout menu: Published and Mine,
rename/publish/default/delete shown only where they would be allowed, and
a dirty dot computed by comparing the live config against the one the pivot
was applied from, since restore() fires the change event itself.
Existing localStorage lists are lifted into pf.layout on first load.
PUT /sources/:id/default-layout is removed.
