feat(fusion_claims): expand dashboard with this-month, pipeline, aging, recent exports + full-width

Adds 4 new sections:
- This Month rollup: submitted/approved/delivered/billed counts MTD
- Pipeline $ by stage: pre-submit / submitted / approved / ready-to-bill amounts
- Aging buckets: 30-59d, 60-89d, 90+ days
- Recent ADP Exports: last 5 with totals

Also overrides Odoo's form-sheet max-width on .o_fc_dashboard so the
dashboard uses the full browser width.
