refactor(data-access): remove TVP code and simplify SearchModel

- Remove all List<*FilterEntry> properties and *FilterEnabled computed properties from SearchModel
- Delete TableValuedParameterExtensions.cs
- Delete entire FilterEntries folder and all filter entry model classes
- Delete FilterHandlers folder and all filter handler classes
- Delete IFilterHandler interface and FilterResult model
- Update MisQueryBuilder to use SQL extraction functions instead of model properties
- Update SearchProcessor to get ExtractMisData from database using fn_GetSearchExtractMisData
- Update DependencyInjection to remove filter handler registrations
- Delete obsolete tests for TVP extensions and filter handlers

Filter criteria are now stored as JSON in Search.Criteria column and extracted using SQL functions (fn_GetSearch*) during query execution.
