- Introduced `Holding::CostBasisReconciler` to manage cost basis resolution logic.
- Added user interface components for editing and locking cost basis in holdings.
- Updated `materializer` to integrate reconciliation logic and respect locked holdings.
- Extended tests for cost basis-related workflows to ensure accuracy and reliability.
* Fix cost basis calculation in holdings controller

- Refactored `persist_holdings` to separate and conditionally upsert holdings with and without cost_basis.
- Updated `avg_cost` logic to treat 0 cost_basis as unknown and return nil when cost_basis cannot be determined.
- Modified trend and investment calculation to exclude holdings with unknown cost_basis.
- Adjusted `average_cost` formatting to handle nil values in API responses and views.
- Added comprehensive tests to ensure cost_basis preservation and fallback behavior.
- Localized `unknown` label for display when cost_basis is unavailable.
