Add ability to retrieve specific comments for reconciliation process

Update routes to use a new method for fetching a single reconciliation comment by ID, replacing the previous approach of fetching all comments and filtering client-side. This change is reflected in both `routes.ts` and `storage.ts`, where a new `getReconciliationCommentById` method is introduced in the `IStorage` interface and implemented in `DatabaseStorage` and `MemStorage`.
