PasswordHasher: retarget net10.0, fix the benchmark project's absolute HintPath (#2165)

- All three projects move from net8.0 to net10.0.
- PasswordHasher.Benchmark.Tests referenced Microsoft.Extensions.Identity.Core
  through an absolute Windows HintPath pinned to SDK 8.0.4, so it built on one
  machine only. Replaced with <FrameworkReference Include="Microsoft.AspNetCore.App" />,
  which is how a non-web project reaches Identity.Core.
- Package lifts, all read from NuGet on 2026-08-30: Microsoft.AspNetCore.OpenApi
  8.0.4 -> 10.0.11, Swashbuckle.AspNetCore 6.4.0 -> 10.2.3, BenchmarkDotNet
  0.13.12 -> 0.15.8, NUnit 3.14.0 -> 4.6.1, NUnit3TestAdapter 4.5.0 -> 6.3.0,
  NUnit.Analyzers 3.9.0 -> 4.14.0, Microsoft.NET.Test.Sdk 17.8.0 -> 18.9.0,
  coverlet.collector 6.0.0 -> 10.0.1. The tests already use the constraint model
  (Assert.That), so the NUnit 3 to 4 move needed no assertion rewrites.
- One comment in CustomerService.Login() saying the sample ignores the
  SuccessRehashNeeded signal deliberately.

Build 0 errors and 8/8 tests pass on SDK 10.0.302 / runtime 10.0.10.
