feat: reports improvement

[RLRama]

Description

This PR introduces:

• new headers for all the program reports,
• update queries for the two 'Programa Sumar - ...' and the two 'Recupero - ...' reports (1, 4, 5, 6)
• extraction of the method used for calculating the BMI in the 'Sumar General' report
• code refactoring (reduction of boilerplate, creation of common utilities), and
• fixes error when downloading report 2 (a date formatter that didn't work properly).

The affected reports are the following:

1. Programa Sumar - General - 12.12.2020 - 12.12.2024.xls
2. Epidemiología - Vigilancia epidemiológica - 12.12.2020 - 12.12.2024.xls
3. Epidemiología - Notificación colectiva - 12.12.2020 - 12.12.2024.xls
4. Recupero - Obras sociales - 12.12.2020 - 12.12.2024.xls
5. Recupero - Odontológico - 12.12.2020 - 12.12.2024.xls
6. Programa Sumar - Odontológico - 12.12.2020 - 12.12.2024.xls

NOTES: test date range is arbitrary, and the reports were generated before the query updates (results may differ).

Changes

This reunites all the methods shared between program reports and the upcoming reports refactor, so boilerplate is reduced. The controllers access routes are left intact, so front-end report generation should work correctly with no required changes.
