* Ensure legacy event foreign key is removed from the states table
If the system ran out of disk space removing the FK, it would
fail. #121938 fixed that to try again, however that PR was made
ineffective by #122069 since it will never reach the check.
To solve this, the migration version is incremented to 2, and
the migration is no longer marked as done unless the rebuild
/fk removal is successful.

* 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

* Ensure states table rebuild still happens if the event_id index was removed
If ix_states_event_id was removed by the foreign key still
exists, the states table would not get rebuilt. This should
not happen under normal circumstances and seems to only be
possible if the index was removed manually or Home
Assistant was restarted forcefully in the middle
of a previous migration from years ago.

* mysql wont allow at that point but thats ok as long as its gone at the end
