Landscape BoL was splitting the signature row down the middle —
boxes half on page 1, half on page 2. Two complementary fixes:
1. **Per-element rule**: added `page-break-inside: avoid` +
`break-inside: avoid` to `.sig-box` (both portrait + landscape
styles) so an individual signature box can never split across
pages.
2. **Wrapper rule**: introduced `.fp-keep-together` utility +
wrapped the BoL's certification statement + signature row in
it, so the whole "sign here" block moves to the next page as
one unit if it doesn't fit. Also applied
`page-break-inside: avoid` to `table tr` so cargo lines don't
split mid-row either.
Lives in shared `report_base_styles.xml` so any FP template that
opts into `.fp-keep-together` benefits automatically.
