Add archived + archived_at columns to PatientSession (setArchived stamps the
time). findByRecord/countByRecord accept an archived filter (default all to
keep existing callers, incl. the discount visit-count, unchanged); the
sessions GET reads ?filter=active|all|archived, defaulting to active so
archived visits are hidden. updateSession accepts { archived }. Records are
kept, only hidden. Verified end-to-end; docs updated.
