refactor(jobs): gate fp.job lifecycle hooks on fp_jobs_migration context

Migration script now sets context fp_jobs_migration=True before
creating fp.job records. action_confirm and button_mark_done check
this flag and skip side-effects (portal job creation, QC check,
racking inspection, delivery, certificate, notification dispatch)
when migrating.

Without this, the migration would double-create portal jobs / QC
checks / racking inspections — once via bridge_mrp's original
create on the source MO, once via jobs module's lifecycle hook on
the new fp.job mirror. With the gate, the migration script
explicitly rebinds the existing dependents via x_fc_job_id.

Manifest 19.0.2.0.0 → 19.0.2.1.0.
