feat: add provider column, commission tracking, and report provider filter

- Claims & Payments: save npiProviderId when submitting MH claim; sync between claim and payment on update
- Claims table: add Provider column showing rendering provider name
- Payments table: add Provider column + purple Commissioned badge on status
- Claim edit modal: add Rendering Provider dropdown (defaults to Mary Scannell)
- Payment edit modal: add Rendering Provider dropdown + Commissioned metadata display
- Reports page: add Provider filter dropdown (dynamic from NPI providers settings)
- Reports page: remove Collections by Doctor report type and Select Doctor dropdown
- Commission section: new section in reports page with date range + provider filter, shows eligible paid claims/payments per provider, multi-select checkboxes, Pay Commission modal with print + save, marks payments as commissioned so they are excluded from future cycles
- DB: add CommissionBatch and CommissionBatchItem tables; backfill Payment.npiProviderId from linked claims
- Backend: PATCH /api/payments/:id/provider syncs to linked claim; PUT /api/claims/:id syncs to linked payment; new /api/commissions routes
