* fix(server): describe EXPLAIN statements so bind parameters work

`do_describe_inner` only planned `Insert`/`Query`/`Delete`, so
`EXPLAIN` and `EXPLAIN ANALYZE` fell through to the non-plan branch
and had no parameter-type inference. At Bind time the Postgres
handler then reported `unsupported_parameter_type` even though the
inner query would have worked on its own.

Recurse one level into `Statement::Explain` so that an EXPLAIN
wrapping a plannable statement goes through the same describe path.
Adds a tokio-postgres integration test that exercises
`EXPLAIN`/`EXPLAIN ANALYZE` over the extended query protocol.

Fixes #8029

* refactor(server): extract plannable-inner check into closure

Reduce duplication between the direct match and the EXPLAIN inner match
by factoring out is_inner_plannable. Behaviour unchanged.
