Also fixes formatting for per license price and moves the billing
schedule to be above this line so that it's clearer the per license
price is based on the billing schedule.
Moves the section in support views for any current plan details
to a new template: `templates/analytics/current_plan_details.html`.
Also, updates the PlanData dataclass to have a boolean that checks
if the current plan tier is the self-hosted legacy plan.
