[QRQC_2] No explicit any in twenty-server (#12068)

# Introduction

Added a no-explicit-any rule to the twenty-server, not applicable to
tests and integration tests folder

Related to https://github.com/twentyhq/core-team-issues/issues/975
Discussed with Charles

## In case of conflicts
Until this is approved I won't rebased and handle conflict, just need to
drop two latest commits and re run the scripts etc

## Legacy
We decided not to handle the existing lint error occurrences and
programmatically ignored them through a disable next line rule comment

## Open question
We might wanna activate the
[no-explicit-any](https://typescript-eslint.io/rules/no-explicit-any/)
`ignoreRestArgs` for our use case ?
```
    ignoreRestArgs?: boolean;
```
