feat(configurator): Phase E — SO list view uplift

E1/E2/E3/E4: list view gets new togglable columns for
- x_fc_wo_completion (e.g. '3/5'): count of completed vs total WOs
- x_fc_invoiced_amount (Monetary): sum of posted customer invoices
  minus credit notes
- x_fc_margin_amount + x_fc_margin_percent: reuses Phase D8 computes
- x_fc_is_blanket_order toggle

New sale.order.search view (sale.order.search.fp) with preset
filters: My Orders / Open / Confirmed / Done / Blanket / Has Rush /
Overdue, plus group-bys for Customer / Status / Customer Deadline.

Bumped to 19.0.7.1.0.
