The TIMESTAMP data type is used for values that contain both date and
time parts. TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to
'2038-01-19 03:14:07' UTC.

A Forever lib class was included to handle future dates for PostgreSQL
and MySQL, also changes were made to DeployToken to enforce Forever.date

Also removes extra conditional from JwtController

- Adds a default on expires_at datetime
- Modifies deploy tokens views to handle default expires at value
- Use datetime_with_timezone where possible
- Remove unused scopes

Also, fixes broken specs

We use controller actions to pass a newly created token and errors

Also:
- Changes scopes from serializer to use boolean columns
- Fixes broken specs

- Remove extra method for authorize_admin_project
- Ensure project presence
- Rename 'read_repo' to 'read_repository' to be more verbose

- When using 'read_repo' password and project are sent, so we used both
  of them to fetch for the token
- When using 'read_registry' only the password is sent, so we only use
  that for fetching the token

Also fixes spec failures on presenter and docs

- Keep 'Deploy Section' open upon save, otherwise the token might get
  lost
- When an error appears, display the error inside the form and also keep
  the Deploy Section open
- Changue copy of revoke modal

This will allow to download a repo using the token from the DeployToken

Includes:
- Model, factories, create service and controller actions
- As usual, includes specs for everything
- Builds UI (copy from PAT)
- Add revoke action

Closes #31591
