chore(deps): upgrade Marten to 9, Duende IdentityServer to 8 and remaining packages

[falberthen]

Bumps:

• Marten 8.22.1 -> 9.30.0
• Duende.IdentityServer 7.4.6 -> 8.0.6,
• EF Core, Npgsql, Swashbuckle, Asp.Versioning, Ocelot, Kiota, Polly, Confluent.Kafka,
  OpenTelemetry and NSubstitute.

No behavior change intended. Everything here is what those two majors required.

Duende 8

• IProfileService takes a CancellationToken on both methods.
• SAML tables added to both DbContexts, so two additive migrations were needed.
• adds EntityFrameworkCore.Design, without which dotnet ef cannot run.

Marten 9

• projections moved to the compile-time source generator: partial classes with conventional Apply methods instead of fluent ProjectEvent registration.
• IdentityAttribute and AutoCreate moved to JasperFx; Newtonsoft support was extracted into the Marten.Newtonsoft package.
• aggregate Apply methods must be public, or the generated aggregation code cannot reach them and AggregateStreamAsync returns null with no error.
• aggregates are rehydrated without field initializers, so the uncommitted-events queue is created on first use
• synchronous data access was removed; three handlers moved onto the existing IQuerySessionWrapper
