Required because fp.job.card_state (stored) has @api.depends including
active_step_id.area_kind. When step.area_kind changes, Odoo's trigger
chain searches fp.job by active_step_id — non-stored fields can't be
queried in WHERE clauses, raising ValueError("Cannot convert ... to
SQL because it is not stored").
Caught during entech deploy of 19.0.10.25.0/post-migrate.py Phase 3
(steps._compute_area_kind() failed on first run). store=True makes
the column searchable and the trigger chain works.
