Ensure Default InstanceType is enabled for Default TeamType in clean install (backport #2573)

[github-actions]

Backport of #2573

---

Fixes #2572

Description

Ensures the default instanceType is enabled for the default TeamType in a clean install

This will need backporting once merged.

This also tidies up the TeamType edit dialog:

• removes the 'billing description' field for instances when billing isn't enabled
• improves the heading shown against the individual instance types
• hides the whole features table as it is not functional yet.

Finally, noticed a spurious log message from sequelize around creating the default ProjectStack - we were passing in default values for non-existent properties of the Stack object. Now tidied up.
