Lets operators exclude a course from the aluno export file without
deleting it. Existing courses already marked "Em extinção" are
backfilled to exportar=False by the migration.
- Add Pessoa/Vinculo.atualizado_manualmente flag, set automatically on web CRUD
save; all Gennera/txt import paths now skip records flagged this way instead
of overwriting them
- Vinculo import: finalize step corrects leftover "situacao nao informada"
vinculos to "Desvinculado", pulling carga horaria from censup_carga_horaria
- Generic CRUD list view: click a column header to sort (asc/desc), persists
through pagination; FK columns sort by their related display field
- Rename GENNERA_API_BASE_URL setting to GENNERA_LOCAL_BASE_URL
