[Trunk | Claims API]:
1. Authorization.java: Added methods "boolean isPortalAdministrator()" to check if a user is portal admin via his "AccessToken" cookie.
2. MetricsService.java: In method "calculateMetrics()" (/report/calc) added @CookieParam("AccessToken") String cookie, in order to allow its execution only by portal administrators.

[Trunk | Claims API]: MetricsService.java: In KPI metrics "claims" KPI renamed to "claims_recorded".

[Trunk | Claims API]: MetricsService.java: Added API call methods to calculate and return metrics for claim KPIs (only /report/metrics is needed for Prometheus).

[Trunk | Claims API]: ClaimsService.java:
1. [Bug fix] Call "this.emailSender.getManagerUtils().isCommunityManager()" instead of "this.emailSender.getCommunityUtils().isCommunityManager()"
2. In method "getUserEmailNotificationPreferences()" (/users/notification) set notification.setOpenaireName with openaireId (we do not query community API anymore and we do not have community name).

Get notifications
return 404 if not found
403 if no manager or curator

Do not initialize notifications if nothing found in the db - Return 204

Claim Service:
Notifications:
- allow save/ get notifications for community curators
- add method to compose 200 response
- return 403 if user is not among the managers or the curators

Claims Service: get Community claims:
Add check if user is manager in communityAPI

Create functions for common code:
Authorization: hasBasicAuthorization
Claims Service: getInfoAndBuildClaim that gets jsonObjects and extracts the information needed for "buildAndInsertClaim"

-Rename HelloWorldService to ClaimsService
-Remove methods for communites and ISLookUpService imports
