Allows users to toggle the use of fake orders for live trading during debugging, enhancing testing capabilities. This feature reads/writes orders from the local file system, enabling controlled simulations. Also, introduces file caching to improve performance when fake orders are enabled.

This PR needs a bit of context.
Someone on Discord had a WTB order for this item where the SMA was around 122 plat, while people were buying it for ~70 plat. QF placed a WTB order around that lower price. Later on, someone raised the price to 110 plat, which was >= than the current WTS orders.
Instead of rejecting that increase, QF also raised its WTB order to 110 plat. In this case, the user had
max_total_price_capset to-1.Issue
When Max Total Price Cap is disabled, it's still being used as a condition for multiple branches, even ones that aren't related to the knapsack logic. This causes all the price filters to be skipped.
What this PR does
This PR removes the
max_total_price_capchecks from those unrelated branches and adds logging so it's clear why it was skipped.
