Adds SlpModularCms.Api.Slave for local master/slave dev testing (Unit 1)

Relocates ModuleOrchestrator, ServiceCollectionExtensions, and
ApiPrefixConvention from SlpModularCms.Api into SlpModularCms.Core.Hosting
so a new Master-less SlpModularCms.Api.Slave host project (ports 5285/7222)
can share the same bootstrap code without duplicating it. This lets a
developer run a master instance and a slave instance side by side locally
to test the master/slave connection, without touching the existing
master/slave protocol itself.

Relocates the two orchestrator/convention test files from
Modules.Identity.Tests to Core.Tests, dropping an incidental
ProjectReference to SlpModularCms.Api that existed only for those tests.

# Components — Local Dev Master/Slave Setup
## 1. `SlpModularCms.Core.Hosting` (new namespace within existing `SlpModularCms.Core` project)
**Purpose**: Single, shared home for the ASP.NET Core host bootstrap/orchestration code that both the master and slave API hosts use identically.
**Responsibilities**:
- Discover and instantiate `IModule` implementations from the host's own build output directory (unchanged behavior).
- Register core cross-cutting services (DB context, Identity, JWT auth, authorization policies, exception handling, API versioning, OpenAPI, CORS, rate limiting) shared by every instance regardless of which optional modules (e.g. `Modules.Master`) are present.
- Apply the `api/v1` route prefix convention to all discovered controllers.
**Interfaces**: Unchanged public API — `ModuleOrchestrator` (class), `AddCoreInfrastructure`/`AddCmsCors`/`AddCmsRateLimiting` (extension methods on `IServiceCollection`), `ApiPrefixConvention` (implements `IApplicationModelConvention`). Only the namespace moves (`SlpModularCms.Api.Extensions`/`SlpModularCms.Api.Infrastructure``SlpModularCms.Core.Hosting`).
**Not responsible for**: Any module-specific business logic — modules remain fully self-contained (`Modules.Master`, `Modules.Availability`, `Modules.Identity`).
## 2. `SlpModularCms.Api` (existing project, master host)
**Purpose**: The main CMS instance — full stack, including the Master module, used for day-to-day development and as the "master" side of a local master/slave test.
**Responsibilities**: Unchanged from today. `Program.cs` now sources `ModuleOrchestrator`/`ServiceCollectionExtensions`/`ApiPrefixConvention` from `SlpModularCms.Core.Hosting` instead of its own local files.
**Interfaces**: No change — same controllers, same routes, same behavior. Its own copies of `ModuleOrchestrator.cs`, `Extensions/ServiceCollectionExtensions.cs`, `Infrastructure/ApiPrefixConvention.cs` are deleted (moved to Core).
**Project references**: `Core` (now including the hosting code), `Modules.Availability`, `Modules.Identity`, `Modules.Master` — unchanged set, just implicitly picks up `Core.Hosting` via the existing `Core` reference.
## 3. `SlpModularCms.Api.Slave` (new project)
**Purpose**: A minimal, Master-less host used purely as a local target for testing the master↔slave connection. Not intended for end-user CMS administration beyond what's needed to validate connectivity.
**Responsibilities**: Bootstraps identically to `SlpModularCms.Api` (via `Core.Hosting`), but its build output never contains `SlpModularCms.Modules.Master.dll`, so `ModuleOrchestrator.DiscoverModules` never loads the Master module for this instance.
**Interfaces**: Same shape as `SlpModularCms.Api` (`Program.cs` calling into `Core.Hosting`), minus anything Master-specific (there is none in `Program.cs` today — the exclusion works purely through the project-reference/build-output mechanism).
**Project references**: `Core`, `Modules.Availability`, `Modules.Identity`. Deliberately **no** reference to `Modules.Master`.
**Configuration**: Own `appsettings.json` / `appsettings.Development.json` / `appsettings.local.json` (gitignored) and own `launchSettings.json` (ports 5285 HTTP / 7222 HTTPS), per FR-2 in requirements.md.

Text alternative: Two host projects (`SlpModularCms.Api` and the new `SlpModularCms.Api.Slave`) both depend on `Core` (which now includes the shared hosting/bootstrap code) and on `Modules.Availability`/`Modules.Identity`. Only `SlpModularCms.Api` additionally depends on `Modules.Master``SlpModularCms.Api.Slave` deliberately omits that reference. All three module projects depend on `Core`.
