"""config.get / config.set must honor params.profile (issue #95760).

A single dashboard backend in desktop app-global remote mode serves every
profile. projects.* RPCs already bind params.profile via @_profile_scoped;
config.get / config.set did not, so reads and persistent writes used the
launch profile's config.yaml for every focused profile.
