docs: record the owner's decisions on routes, compatibility and inbound roles

panel-redesign.md gains four sections. Routes: paths follow the new names
and structure (/overview, /outbound/..., /inbound/..., /server/...,
/account), with one <page>/fragment name, the application form as a
single POST and TestRoutesFollowNavigation. No compatibility: the redesign
is 2.0.0, old paths are removed without redirects, the migration chain is
replaced by one baseline and 2.0 starts from an empty data directory (the
only live installation is the owner's); schema-squash ships as a step of
this plan without its upgrade gate. Who sees what: a domain administrator
manages assigned inbound domains, granted separately from outbound
(user_inbound_domains, per-domain authorization under /inbound/). Room for
roadmap items: where antispam lists, quarantine and preflight land, and
that a feature's screens are drawn mockup-first in this system.

Mockups: the Reload configuration box the first pass missed (now on
Server > Health), the flash component and the sp-help link that replaces
the help drawer, and the user form with two assignment lists. The
antispam plan no longer points its mockup at the superseded panel-ui
folder. Checklist 3/21.
