[PM-18235] Add PersonalOwnershipPolicyRequirement (#5439)

* Add PersonalOwnershipPolicyRequirement for managing personal ownership policy

* Add tests for PersonalOwnershipPolicyRequirement

* Register PersonalOwnershipPolicyRequirement in policy requirement factory

* Update ImportCiphersCommand to check PersonalOwnershipPolicyRequirement if the PolicyRequirements flag is enabled

Update unit tests

* Update CipherService to support PersonalOwnershipPolicyRequirement with feature flag

- Add support for checking personal ownership policy using PolicyRequirementQuery when feature flag is enabled
- Update CipherService constructor to inject new dependencies
- Add tests for personal vault restrictions with and without feature flag

* Clean up redundant "Arrange", "Act", and "Assert" comments in test methods

* Refactor PersonalOwnershipPolicyRequirementTests method names for clarity

- Improve test method names to better describe their purpose and behavior
- Rename methods to follow a more descriptive naming convention
- No functional changes to the test logic

* Remove commented code explaining policy check

* Refactor PersonalOwnership Policy Requirement implementation

- Add PersonalOwnershipPolicyRequirementFactory to replace static Create method
- Simplify policy requirement creation logic
- Update PolicyServiceCollectionExtensions to register new factory
- Update ImportCiphersCommand to use correct user ID parameter
- Remove redundant PersonalOwnershipPolicyRequirementTests

* Remove redundant PersonalOwnershipPolicyRequirementTests

* Remove unnecessary tests from PersonalOwnershipPolicyRequirementFactoryTests
