Ask Alma about a contact, choosing the area

There is one counsellor, Alma. The slug says which area she answers with: alma (and memchats) let her detect it from who the contact is and what the exchange is about, while legal, relaciones, conocer and negocio set it explicitly. The five retired advisor slugs are kept for backwards compatibility with existing API tokens and the published MCP server, and map onto the areas: lexiel to legal, amoriel and pactiel to relaciones, cupiel to conocer, proxiel to negocio. No area depends on the plan: all four are available on every plan, Free included. Same pipeline and same quota as POST /api/v1/alma/respond (consumes one LLM query from the plan quota), returned in the flat { answer, advisor, contact_id } shape older clients read.
