Pulls the forms for updating the billing collection method and
generally modifying the current plan to a separate template.
Uses the shared template to render these forms for both the
remote server and any attached remote realms.
If there are remote realms attached to the remote server, adds
the forms to be able to update sponsorship requests, approve
sponsorship and update a discount.
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.
Updates `get_plan_type_string` for RemoteZulipServer plan types and
capitalizes the strings used for Realm plan types.
Also changes the string for Realm.PLAN_TYPE_STANDARD_FREE to be
"Standard free" instead of "open source" as that is used for any
100% sponsored organization, which is not restricted to open-source
projects.
Removes the support actions for changing a remote server's default
discount and sponsorship pending states if the remote server is on
the sponsored plan type.
This calculates the largest amount of messages sent within a month for
the last 3 months. The query is targeted for the specific use-case in
this function - for finding the count for a specific server. For
calculating this in bulk for a large number of remote server an
adapted, bulk query will be needed - rather than running this one in a
loop, which would likely be very inefficient.
