fix: Improve spacing in Connector title block
fix: Improve spacing in Connector title block

The `<Dialog />` `cozy-ui` component used by *Harvest* has a flaw in its design
In small screens, it will display (probably by error) the modal title in a `padding: 12px 16px 16px 48px` setting
This is highly undesired and unfortunately we can't add class or any styling props to this part of `<Dialog />`
At the time of this commit, the simplest way to handle the issue is to override the `.dialogTitleWithBack` class
This way we can apply our desired design in a limited scope: only *Home*, only *Mobile*
