This commit introduces a seperate `page_params` file for billing module
since we only use certain page_params in billing module only that it does
not make sense to include them in the main `page_params.ts`.
Also introduced `zpage_billing_params` for proper testing new `page_params`
in billing module.
exempt_from_license_number_check was initially added allowing
organizations with it enabled to invite new users above their number of
licenses.
However, an organization with this permission enabled,
cannot upgrade if they weren't on a plan already - because when choosing
Manual license management, you cannot enter a number of licenses lower
than the current seat count. However, an organization like that probably
already has some users that they get free of charge - and thus they need
to be able to enter a lower number of licenses in order to upgrade.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
