fix: use install_with_observer for B20Factory/PolicyRegistry

base/base dropped the plain install() shims for B20Factory and
PolicyRegistryPrecompile in favour of the observed variants (only
install_with_observer remains). Our inject_precompiles still called the
removed B20Factory::install / PolicyRegistryPrecompile::install, so the
patched base-anvil build failed with E0599 on base/base's fork-test CI.

Switch both to install_with_observer with a no-op observer (metrics are
scoped to the B-20 token call path, which anvil doesn't wire up), matching
provider.rs. B20Factory::install_with_observer also takes the BaseUpgrade,
so thread Beryl through like the lookup. Bump the base/base pin to current
main (cc8ee38) so this compiles against the observer-only API.
