chat: add simplex_name to contact_profiles and group_profiles

Adds nullable simplex_name TEXT column and partial UNIQUE
(user_id, simplex_name) index to both contact_profiles and group_profiles
tables. Distinct from contacts.simplex_name / groups.simplex_name
(M20260603), which carry the user's locally-known label set by the
prepare-via-name path; the new columns will carry the peer's broadcast
claim received via XInfo / XGrpInfo (wired up in following commits).
