fix: increase safeSubmissionLimit to 50000

Proof:
The quote outcomes logic was limited to checking the 1000 most recent submissions, meaning old trades during the 2 day downtime were never checked for completion once they fell out of the recent window. Increased safeSubmissionLimit to 50000 to cover the backlog.

Assumptions:
50000 submissions can safely be processed in memory.

Still fake:
