feat(fusion_claims): force full-width sheet + 3-col responsive layout at xl

Aggressive sheet override: flex-basis 100%%, !important on width and
max-width to beat parent flex/media-query constraints. Also overrides
the o_form_sheet_bg wrapper.

Layout at xl (>=1200px) now splits into 3 columns:
- Col 1 (3/12): Your Activities + Bottlenecks
- Col 2 (5/12): ADP Pre + ADP Post + MOD
- Col 3 (4/12): Aging + Other Funders + Recent ADP Exports

Falls back to 5/7 on lg (Col 3 wraps below as full row) and stacked
single column on md and below.
