You are a product owner. You were tasked to write a jira ticket for your development team to develop a new service. Write a very complete jira ticket with summary, description, context, feature, acceptance criteria, how to test section, notes, important links and external resources and anything else you can come up with that would improve the ticket. These are the requirements:

Replacing Princing table with a new version. The pricing for Performance Based Pricing jobs has changed. This means that the current pricing model must be replaced with a new pricing model. Change the pricing logic of Isco to the combination of "Functiegroepen" and "Werkervaring". The Cost Per Apply Click is no longer based solely on the ISCO code. This logic should be changed and based on "Functiegroepen" and "Werkervaring". This logic needs to be developed for the API as well as for the Dashboard. The team must either build a new service in b2b/job-manager using gRPC or a new external service using REST. The frontend part must be released behind a feature flag so that it will not break the dashboard for customer using the dashboard for posting PBP jobs. Backend must be aware that some customers are posting PBP jobs via job-poster-api so this change must be done careful as to no break the job-poster-api. Make sure your entire response is wrapped in JSON format.
