Refactor insurance share calculation logic in PatientService

- Consolidated the calculation of patient and insurance shares into a single method using BillingCalculator.
- Introduced new fields in PatientSession to store breakdown of insurance shares and patient share.
- Updated the API responses to include the new fields for consistency across payment, invoice, and claims dashboard.
- Added migration to backfill existing sessions with appropriate values for the new fields.
- Implemented tests to ensure the correctness of the new logic and verify that the breakdown sums to the gross total.
- Redesigned the claims dashboard to provide a more user-friendly overview of patient claims and their statuses.
