Add env override for Add/Manage License button

[AlexGaillard]

Scope

What's changed:

• A new env override LICENSE_KEY_MANAGEMENT_ENABLED has been added with default true
• Setting this to false will disable the "Add/Manage License" button on the license page
• This will also disable management of the license via the api
• This change required an update of the @directus/license package, which has already been published with the change
• Messaging for why management of license has been extended to account for both key in env and disallowed by env in both the "Manage License" button and the "Deactivate License" button

Potential Risks / Drawbacks

• Changes to license manager cause some weird behavior

First pass review

• Are there any E2E tests I should update? New ones should be added to back this behavior.
• Should we document this? Yes

Any context for showing env managed if general management is off?

I would expect messaging should depend on whether management is enabled. If management is disabled, we should show that license management is not allowed. If management is enabled but the source is env, then we can show the env message.

As a side note, this also does not show the env manage message if license is enabled but source is env

[AlexGaillard]

There wasn't originally, but now with how the editable is worked out on the backend it makes sense to show them this way otherwise when the edit is restricted purely by the env license, the frontend can't tell and will show “Management of your license key is disabled by your environment settings”

[ComfortablyCoding]

I see no issue showing "Management of your license key is disabled by your environment settings” irrespective of license source or existing license?

[ComfortablyCoding]

Let's rename this inline with any rename to the env var for clarity

renamed to isLicenseKeyManagementEnabled
