[CONNECTED_ACCOUNT_BREAKING_CHANGE] Unify connected account permissions (#20732)

# Introduction
This PR is a followup of https://github.com/twentyhq/twenty/pull/20673

It aims to unify the authentication/permissions layer with all the
connectedAccount interactions across the application

## Deprecate
- findAll
- findById

## Email sync
An user can only sync the message of his own connected account

## Workflow email
- Related https://github.com/twentyhq/private-issues/issues/478
- Only reauthorize owned account
