refactor(client): keep settings constants and schemas off the client contract surfaces

The /client entry of a UI plugin exports no values beyond what cordis
loading needs; the theme constants block returns to type-only re-exports,
the per-namespace schemas move into the shared *-settings modules instead
of widening the host entries, and same-package specs import those internals
directly per the export discipline in packages/client/AGENTS.md.
