feat: chatbot rendering provider override and NPI provider ordering

- AI chat extracts 'with provider <name>' and routes claim to that provider
- Claim form reads provider from sessionStorage before any async effects run,
  preventing saved claim/procedure data from overriding the chatbot selection
- NPI provider settings table shows Provider #1 / #2 labels with up/down
  reorder buttons; Provider #1 is always the default for claims
- Default provider now uses sortOrder instead of hardcoded 'Mary Scannell'
- Added sortOrder column to NpiProvider schema with migration
