[Feature] Add MBES line numbers to Budget

[thetif]

Description and related issues

In order to build the MDBT table, we need to store the MBES line numbers for the different cost categories. These are based on the APD Type, Funding Category, Fed-State Split, and Cost Category. Jerome created this flow diagram to explain which line number goes with what configuration of the above.

MDBT/MBES Classification Flow

We need to store these values in the budget under the activityTotals because they will be different for each activity. They should be determined as part of the budget calculation.

Their schemas should look like

// HITECH (values are always the same regardless of split)
const budgetSchema = new mongoose.Schema({
	...,
        activityTotals: [{
                ...,
	        mbes: {
		        statePersonnel: String, // always 24C
		        expenses: String, // always 24C
		        contractors: String, // always 24D
		        epAmt: String, // always 24E
		        ehAmt: String // always 24F
                }
	}]
});

// MMIS
const budgetSchema = new mongoose.Schema({
	...,
        activityTotals: [{
                ...,
	        mbes: {
		        statePersonnel: String, // DDI - 2A, M&O - 5A
		        expenses: String, // DDI - 2A, M&O - 5A
		        contractors: String, // DDI 2B, M&O - 5B
		        interagencyCost: String // only for M&O - 5C
                }
	}]
})

Acceptance criteria

• create constants for MBES line numbers
• update activityTotals in the Budget schema to save these values
• update the budget calculation to calculate the correct line number based on the APD Type and Funding Category
• save the MBES line numbers to the Budget

Testing criteria

Given	When	Then	Covered
a HITECH APD	the activity has any funding source	mbes should be set to mbes: { statePersonnel: '24C', expenses: '24C', contractors: '24D', epAmt: '24E', ehAmt: '24F' }
a MMIS APD	the activity has funding category DDI	mbes should be set to mbes: { statePersonnel: '2A', expenses: '2A', contractors: '2B', interagencyCost: '' }
a MMIS APD	the activity has funding category M&O	mbes should be set to mbes: { statePersonnel: '5A', expenses: '5A', contractors: '5B', interagencyCost: '5C' }
