App.jsx fell back to versions[0] when localStorage held no selection, and
the version list is ordered created_at DESC -- so a fresh browser landed on
whatever version was created last. That is a scratch scenario as readily as
the plan, and sales accounts, which never pick a version themselves, had no
way back to the one they were meant to read.
pf.version.is_default names the landing version, at most one per source by
partial unique index, the way pf.layout.is_default already works. Setting it
is admin-only and enforced in the route: it decides where everyone else
lands, so it follows the pf.log rule rather than being the version's own
setting like its name.
A stored selection still wins -- the default is the fallback, not an
override, so nobody building scenarios is thrown back to the plan on every
load.
