a plugin owns the routing under its mount

Reverts the manifest route table. Declaring a plugin's URLs to the platform put
the platform in the middle of a decision that is not its own, and it was more
code than what it replaced.

One splat where there were two routes. A splat matches zero segments, so the
bare route still works, and the plugin reads its own position off the location.
The platform owns where a plugin starts and nothing after it — the same line
mountPrefix already draws around its API.

A SPLAT, so the whole subtree is the plugin's.
It REPLACES the pair below rather than adding to it: the plugin has said what its URLs
are, so a guessed `/:section` alongside them would be a route nothing links to, matching
ahead of a declared one and rendering the wrong layout.
It was a pair — the bare route and `/:section` — which gave a plugin exactly one segment and
made the platform the author of what it meant. Anything deeper had to go in the query
string, and `/fofos-admin/layout/header` was not expressible at all.
The layout key carries the path pattern, so two routes arranged differently remember
their own dividers. A route on the screen's own layout keeps the screen's own key — its
sizes are the ones the user already set.
