See ~~CAMEL-12058~~

We should improve the FileIdempotentRepository to let it lookup in the file store as fallback if a key is not in the 1st-level.

Also the number of items in the store should not be limited to max size of the 1st-level cache. The tradeoff to check the file if 1st-level cache was a miss is okay.

The file-store should also store the entries in the order they are added.

If the file store max limit is hit, it should re-balance to file store to remove any potential duplicate items
