Additive migration: nullable profiles.gender / chart_profiles.gender with a
female/male CHECK, owner-only via existing table RLS, column grants mirroring
the neighbouring birth columns (service_role for the account PATCH, no
admin_runtime). Account PATCH/GET, people POST/PUT/GET, subject resolution
and the consult route carry each person's own value; a people write only
touches gender when the key is sent. DB test runs in the gate's DB job.

Chart, ephemeris, reports, daily language, consult, and synastry read birth data only through resolveSubjectBirth. The current person is a request parameter outside Home(). /people replaces the settings chart pane, and deleting someone removes that person's chats and reports.
