Fix synthflesh patch unhusking, improved feedback (#90514)

- Fixes application of synthflesh patches for unhusking mobs, adjusts
purity to allow one medigel to dehusk one corpse.
- Improved information on containers about the requirements to unhusk,
and added feedback for the player to help guide the proper usage of the
synthflesh.
- It will give a warning if they are using it in a method that would
waste the synthflesh and fail to unhusk.

- Fixes patches.
- Provide better feedback on why failure to dehusk occurs. Currently the
player is provided no information about why it failed (such as purity,
quantity, burn damage) nor how to resolve it.
