[PM-23580] Security Task Metrics (#6164)

* add metrics endpoint for an organization to return completed and total security tasks

* refactor metrics fetch to use sql sproc for efficiency rather than having to pull all security task data

* add separate response model for security task metrics endpoint

* Pascal Case to match existing implementations

* refactor org to organization for consistency with other methods

* alter security task endpoint:
- remove "count" from variable naming
- update sproc naming

* remove enablement check

* replace orgId with organizationId
