[AC-1070] Enforce master password policy on login (#2714)

* [EC-1070] Add API endpoint to retrieve all policies for the current user

The additional API endpoint is required to avoid forcing a full sync call before every login for master password policy enforcement on login.

* [EC-1070] Add MasterPasswordPolicyData model

* [EC-1070] Move PolicyResponseModel to Core project

The response model is used by both the Identity and Api projects.

* [EC-1070] Add response model to verify-password endpoint that includes master password policies

* [AC-1070] Introduce MasterPasswordPolicyResponseModel

* [AC-1070] Add policy service method to retrieve a user's master password policy

* [AC-1070] User new policy service method

- Update BaseRequestValidator
- Update AccountsController for /verify-password endpoint
- Update VerifyMasterPasswordResponseModel to accept MasterPasswordPolicyData

* [AC-1070] Cleanup new policy service method

- Use User object instead of Guid
- Remove TODO message
- Use `PolicyRepository.GetManyByTypeApplicableToUserIdAsync` instead of filtering locally

* [AC-1070] Cleanup MasterPasswordPolicy models

- Remove default values from both models
- Add missing `RequireLower`
- Fix mismatched properties in `CombineWith` method
- Make properties nullable in response model

* [AC-1070] Remove now un-used GET /policies endpoint

* [AC-1070] Update policy service method to use GetManyByUserIdAsync

* [AC-1070] Ensure existing value is not null before comparison

* [AC-1070] Remove redundant VerifyMasterPasswordResponse model

* [AC-1070] Fix service typo in constructor
