test(api): cover the install endpoints, and make 14 dead guards reachable

/plugins/install and /plugins/install-from-url were tested only at the
PluginStoreManager layer, so the route logic — the queue-versus-direct
branch, schema invalidation, discovery, state and history recording — was
unexercised.

Covering them surfaced the wider form of the body-parsing bug fixed for
the `or {}` handlers in the previous commit. Fourteen handlers read
`data = request.get_json()` and immediately guard with `if not data:
return 400, 'No data provided'`. That guard cannot run: get_json()
without silent=True raises UnsupportedMediaType for a request with no
JSON body, so the catch-all answered 500 "an error occurred; see logs
for details" where the handler plainly meant to answer 400 and say
which field was missing. Every one of these endpoints told a caller who
simply forgot the body to go read the server logs.

All fourteen now use silent=True, so the guard each author already wrote
is the one that runs. This covers /config/raw/main and /config/raw/secrets
among them, whose own bodyless case had the same shape.

The two remaining bare reads are left alone: neither declares what a
missing body should do, so there is no stated intent to honour.

31 install tests plus 17 body tests. The install pair is checked against
each other rather than only individually — the same install logic is
written twice, once in the queue callback and once in the fallback, so
the tests assert both produce identical schema, discovery, state and
history effects. They agree today; the one difference is the success
message wording, which is characterized rather than changed.
