style: rustfmt squad host + adapter files

Formatting-only. Runs the project formatter over the files authored/edited
this session (host lib+tests, adapter item/squad_ext/squad_projection/mod +
projection test). The intentionally-preserved dirty catalog.rs and
pre-existing /club-era host drift beyond these files are out of scope.
