New Service Fee Options

[RaymondO55]

We need the ability to create new flat rate service fee options to ensure accurate associate balances. Some jobs use flat rate service fees that don't work well precisely with the percentage based options we have now.

To achieve this a flat rate field should be included on the creation page for service fees that will accept a number with up to 2 decimal places. The value listed will be the fee owed to us by the associate. We can use the title and description to describe the specific details of the arrangement. @rodolfomartinez please confirm if this function is what we're looking for

This will also require a new field in the service fee overview screen

The complication will be in the service fee calculations. To implement this, if a flat rate option was chosen opposed a percentage the calculation needs to be changed from a percentage of the labour cost to simply be equal to the value entered in the new flat rate field
