When running WT_SESSION::verify against a database using disaggregated storage, if SLS or PALI fails to return a page from the page server or object storage, verify aborts immediately. This prevents verification of the remaining healthy pages in the database.

Verify already has a read_corrupt configuration option (src/btree/bt_vrfy.c:96-97) that allows it to continue past page read failures by saving the error in vs->verify_err and continuing tree traversal (see __verify_tree() at lines 894-908
and 962-976).

We should make sure this also works through the mongodb validate command.
