GET /api/bm/issues/most-expensive endpoint returning top 5 injury issues sorted by totalCost descending.

Hi Amaresh,

I ran and tested the current branch locally.

I was able to verify that the following endpoints work and that the data returned is in the correct format returned with the top 5 results sorted in the correct order.

1. /api/bm/issues/longest-open
   

2. api/bm/issues/most-expensive
   

3. /api/bm/issues/longest-open with query parameters(projectId, startDate, endDate)
   

4. api/bm/issues/most-expensive with query parameters(projectId, startDate, endDate)
