[PACKS] # 4 Show the custom units when displaying the request to the partner
Summary
Show the custom units when displaying the individual request to the partner(assumes [PACKS] #3 is complete)
Why
This is step #4 of adding the ability to specify "packs" versus "individual" for requests
Details
This is for when we show the individual request to the partner, when they save their request. For the lists of requests, see [PACKS] # 6.
The unit should be put between the number and the word "of" (if and only if a non-default unit is selected).
N.B.
All of the changes for PACKS must be implemented behind a flipper flag "enable_packs"
Criteria for completion
- [ ] functionality as described above
- [ ] tests that support the functionality as described above
Background
The following sections have been identified as required for the PACKS implementation. These should be implemented in numerical order.

Nevermind! We are going to do #6 first instead :)
