Fix: reports pdf formatting & extract code duplicate

[RLRama]

Description

This PR introduces a few formatting improvements to the HTML templates used for the PDF generation of the questionnaires response, as well as extracting a duplicate method used for getting a patient's full name as a string.

Changes

1. HTML template changes

• Change header fields "Detalles del paciente" and "Detalles del profesional" to "Datos del paciente" and "Datos del profesional" for all the questionnaires, respectively.
• Change header field "Licencia" to "M.P." (matrícula profesional) for all the questionnaires.
• Removes the "meses" detail of the patient's age in the header.
• Change questionnaire title from "Nombre del cuestionario - Resultados de informe" to ""Nombre del cuestionario - Informe de resultados" for all the questionnaires.
• In the FRAIL report, change syntax to more appropiate one for an item of the test for easier understanding.
• In the FRAIL report, add the assessment result section at the end. This implies the addition of 2 rows to minsal_lr_item table for the relevant item. @DocOc98

2. Function duplicates extraction

• Create a small new @Service currently only used for sharing a function that generates a string with the full name from a Person object. This is consumed by the PDF and the 'get all questionnaires by patient' endpoints.
