feat(EMS-3532): no pdf - application submission - XLSX - worksheets

[ttbarnes]

Introduction ✏️

This PR updates the XLSX generation so that each section of an application has it's on worksheet/tab in the XLSX, instead of single worksheet with a large list and a myriad of conditional index behaviours.

Resolution ✔️

• Create new INDEXES constants for each section of an application.
• Create new SECTION_NAMES constants.
• Remove the original XLSX_ROW_INDEXES approach.
• Update XLSX_HEADER_COLUMNS.
• Update generate.XLSX to generate a worksheet for each section.
• Update mapApplicationToXLSX to return an object structure.
• Update worksheetRowHeights and styledColumns to work with worksheets instead of one single worksheet.

Miscellaneous ➕

• Minor logging improvements.
