[REFACTOR][FRONT]: Remove objectMetadata and fieldMetadata sluggification (#9441)

# Introduction
For motivations and context please have a look to
https://github.com/twentyhq/twenty/pull/9394 whom this PR results from.
In this pull-request we remove any `metadataField` and `objectMetadata`
sluggification. We directly consume `objectMetadata.namePlural` and
`metadataField.name`, ***it seems like that historically the consumed
`metadataField.name`*** are we sure that we wanna change this behavior ?

## Notes
Unless I'm mistaken by reverting the `kebabcase` url formatting we might
be creating deadlinks that user could have save beforehand => Discussed
with Charles said it's controlled risk.
