- Create ownership_costs table for recurring vehicle costs
- Add backend feature capsule with types, repository, service, routes
- Update TCO calculation to use ownership_costs (with fallback to legacy vehicle fields)
- Add taxCosts and otherCosts to TCO response
- Create frontend ownership-costs feature with form, list, API, hooks
- Update TCODisplay to show all cost types
This implements a more flexible approach to tracking recurring ownership costs
(insurance, registration, tax, other) with explicit date ranges and optional
document association.
