Martin Vogel 14def05cfe fix(java-lsp): resolve interface calls to sole concrete impl before type_dispatch ...

A call through an interface-typed receiver (s.area() where s:Shape) hit
java_lookup_method on the interface's OWN abstract method and emitted
lsp_type_dispatch on Shape.area, never reaching the sole-implementer
resolution — so lsp_interface_resolve / lsp_interface_dispatch were never
produced.

Resolve interface dispatch first when the receiver is an interface: a sole
concrete in-project implementer -> lsp_interface_resolve (to that impl's
method, synthesizing the QN when the method registry lacks it); two-or-more
-> lsp_interface_dispatch; ZERO in-project impls -> fall through to
type_dispatch on the interface method, keeping JDK interface calls
(List/Stream/Predicate) strict.

The sole-impl detection is factored into java_find_sole_impl and hardened:
consult the method REGISTRY (the dispatch path's source of truth) since the
per-type method-name array is often empty, match supertypes by full QN OR
bare name (duplicate registry entries list a supertype short in one entry and
fully-qualified in another), and dedup implementers by QN so one class with
two registry entries is not miscounted as two implementers.
