fix(bol): bigger title, shipper info, uniform headers, cargo qty, taller signatures

Five fixes applied to the Bill of Lading and (where relevant) all
report templates:

1. **Bigger title + BoL #** — portrait now uses h2 24pt (was h4 16pt),
   landscape h2 26pt; BoL # ticker is 13/14pt instead of body size.

2. **Shipper info missing** — root cause: `_fp_build_delivery_vals`
   was creating deliveries without `company_id`, so the BoL's
   `<span t-field="doc.company_id.name"/>` rendered empty. Two fixes:
   - Hook now sets `company_id = mo.company_id.id or env.company.id`.
   - Template falls back defensively to `env.company` when
     `doc.company_id` is empty (covers any legacy delivery that
     somehow slips through without it).
   - Backfilled 14 existing deliveries via SQL on entech.

3. **Uniform header backgrounds** — replaced mixed `info-header`
   (gray) + default-th (brand black) headers with a single
   `fp-header-primary` (brand black) across all sub-tables for a
   consistent look.

4. **Cargo description alignment + missing column** — added a QTY
   column (matches landscape variant), pulled from the linked MO
   via job_ref → mrp.production.product_qty. Added `.fp-cell-mid`
   utility class with `vertical-align: middle !important;` and
   applied it to every cargo + info cell so values sit centred
   instead of jammed against the top border.

5. **Signature box too short** — bumped `.sig-box` from 70 → 110 px
   (portrait) / 130 px (landscape), `.sig-line` from 28 → 60/70 px,
   added flex layout so the label sits at the bottom and signers
   have a real space to write in. Lives in the shared
   `report_base_styles.xml` so EVERY FP template benefits, not just
   the BoL.

Verified: BoL portrait renders cleanly at 140 KB with full shipper
block + uniform headers + middle-aligned cargo cells.
