feat: drop calendar repository (#5824)

This PR is replacing and removing all the raw queries and repositories
with the new `TwentyORM` and injection system using
`@InjectWorkspaceRepository`.
Some logic that was contained inside repositories has been moved to the
services.
In this PR we're only replacing repositories for calendar feature.
