feat: add ownership-costs feature capsule (refs #15)
- 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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
