Fixes

• Deleting a user always failed. XpoDxUser.OnDeleting built its role and claim collections without a session, so they used XpoDefault.Session, which XpoDatabase sets to null: UserManager.DeleteAsync threw ArgumentNullException. They use the user's own session now (as XpoDxRole.OnDeleting already did).
• Claims and logins. Removing/replacing a user's claims, removing a login, and adding/removing/replacing a role's claims compared the key via ModelKey(...)/Equals inside the query, which XPO can't translate ("Custom function 'ModelKey' not found", "expression is not supported"). They use criteria with the key as a parameter now.
• GetUsersInRoleAsync: stray ) in the criteria (parser error).
• Mapster, reading user claims: the XPO claim's string key was mapped onto IdentityUserClaim.Id (an int) and threw FormatException; it's ignored now, as for role claims.

Tests

New DX.Data.Xpo.Identity.Tests (xunit, net8/9/10), 17 tests:

• the XPO identity classes on an in-memory database, with XpoDefault.Session null as XpoDatabase leaves it: user and role delete, roles, claims, logins, tokens, upper-case fields;
• the stores as AddXpoMapsterIdentityStores registers them, through UserManager/RoleManager: create, find, password, roles, claims, logins, role claims, delete.

Without the delete fix, 3 of the model tests fail; the store tests found the other fixes. New workflow Tests.yml runs these and the CronJobs tests on push to master and on PRs.

Versions

Bumped the changed packages and everything depending on DX.Data.Xpo.Identity (checked with dotnet pack that the nuspecs pick up the new versions):

Package	Version
DX.Data.Xpo.Identity	26.1.3.37 → 26.1.3.38
DX.Data.Xpo.Identity.Mapster	26.1.3.37 → 26.1.3.38
DX.Data.Xpo.Identity.AutoMapper	26.1.3.36 → 26.1.3.37
DX.Blazor.Identity	26.1.3.30 → 26.1.3.31
DX.Blazor.Identity.Server	26.1.3.28 → 26.1.3.29
DX.Blazor.Identity.Wasm	26.1.3.28 → 26.1.3.29

Merging publishes these through Publish-NuGet-Packages.yml.

Not changed

RegisterIdentityServices.AddStores requires IConfiguration to look up an XpoDatabase it then doesn't use; harmless in a web app, the tests register an empty configuration.
