[Feature Request]: MSSQL extension Query Histroy should be unlimited and searchable

### Feature Description

Currently the SQL server query history is limited and not retained after IDE is closed.
All query history in any database should be saved somewhere physically, retain it's state after IDE is closed and have the ability to search the history by content and date. This would make much easier workflow in case you want to find a query you executed some time ago.

### Problem and Motivation

This would make much easier workflow in case you want to find a query you executed some time ago.

No files, tests, or entry points are named. Start by locating the extension's query-history implementation and trace how history is currently stored and displayed; done means query history is retained after the IDE closes and can be searched by content and date for all databases.
