✨ Set balance to u128 instead of config type on pallet_funding (#394)

## What?
- Remove the `Balance` config type, and replace it for u128

## Why?
- Having to access our fundamental balance type through trait interfaces was making our code unnecessarily bloated. The only reason to have a generic balance type is if our pallet is written to be used in many other blockchains, which is not the case.
- Now we can use directly u128, instead of having to convert with into()
- We were already assuming 99% that it was u128 since it had to implement From<u128>
 
## How?
- Replace BalanceOf<T> with Balance
- Delete all unnecessary conversion
- Remove the generic Balance types from the pallet funding types

## Testing?
Normal tests

## Anything Else?
This will now allow us to use abs_diff for the vesting api
