fix(customeradministration): enhance attribute coverage of queries/mutations

[pranav-new-relic]

Enhances attribute coverage for customer administration and organization management APIs with comprehensive type definitions, query support, and field corrections.

Organization Package

• Renamed Organization → OrganizationManagement for clarity between data types and API client
• Added GetOrganization() query returning organization details (administrator, customerId, telemetryId, etc.)
• Added limitingDataAccessPolicyId to shared account mutations
• Added 579 lines of types:
  • User management (groups, authentication domains, users with filtering/pagination)
  • Authorization management (roles, grants, search containers)
  • Account management (managed accounts)
  • NRDB query types (metadata, results, progress)
  • Actor type for organization-scoped queries

Customer Administration Package

Fixed input filter field types for proper GraphQL schema compliance:

• Changed non-nullable fields to required (In arrays, Eq strings)
• Changed filter structs to pointers where optional (DataAccessPolicyId, Grantee, ScopeV2Type, etc.)

Tutone Configuration

• Added organization query configuration under actor path
• Added field type overrides for new filter types to ensure pointer generation

@copilot based on all of the files changed in this PR as you may find, can you please generate a comprehensive, yet concise description for this PR that I can add to the description field here? You may want to do so by generating a temporary README.md file in the patch that you would open, from which I shall copy the contents and attach to the description of the PR here. Please ensure that we cover key details - the description does not need to be too elaborate, but should be able to briefly explain the changes made here, the packages affected and a gist of things which have moved across such as datatypes, the API files and more.
