Simplify useRichText hook to use synchronous facet detection

Replace async detectFacets with synchronous detectFacetsWithoutResolution,
eliminating the need for loading states, agent dependency, and complex
effect-based resolution. This simplifies the hook from ~30 lines to ~6 lines
and removes the duplicate local implementation from Profile.tsx.
