Narrow sqlite database corruption check to ensure disk image is malformed (#121947)

Browse Source 
* Narrow sqlite database corruption check to ensure disk image is malformed

The database corruption check would also replace the database when it
locked externally instead of only when its malformed.

This was discovered in https://github.com/home-assistant/core/issues/121909#issuecomment-2227409124
when a user did a manual index creation while HA was online
