[AGIPD] [SlopesPC] use send_to_db

Summary

1. There was a bug in the SlopesPC that it was hardcoded to inject constants only for the SPB physical modules (AGIPD1M1).
2. Sphinx tag updated to use feature for wrapping long parsed-literal text in .rst

Steps to reproduce

1. Running Chracterize_AGIPD_Gain_PC_NBC.ipynb with parameter input instrument = "MID"
2. Trying to inject constants with non-available conditions in the database, will show part of the error message in a pdf report.

What is the current bug behavior?

1. After creating constants from MID raw data it is injected to the database for the wrong 16 modules in SPB, not MID
2. CalibrationDBRemote sends back long messages in case of errors related to the database which will not be totally exposed in the pdf report as it is written in parsed-literal section in .rst without proper spaces

Relevant reports:

2. Difference can be shown at the parts for visualising feedback for injecting constants to the database
