Feat: Rearranging Providers

+A provider implementation lives inside the module that owns the data it erases/exports, under
+that module's own `Privacy/` subdirectory (e.g. `Modules\Core\Order\Privacy\OrderDataProvider`,
+`Modules\Core\Customer\Privacy\CustomerDataProvider`) — never inside `Modules\Core\Privacy`
+itself, which only owns the shared contract (`Contracts\PersonalDataProvider`), the request
+lifecycle (`Services\PrivacyManager`/`PrivacyService`), and the DTOs/enums every provider
+returns. This mirrors how this codebase already handles other cross-cutting-but-domain-specific
+code (e.g. a resource's own `Filament/Extensions/` subdirectory) — and matters concretely if a
+module is ever extracted into its own composer package (see `docs/modules.md`): the provider
+that knows how to erase that module's data must travel with it, not get stranded in `Privacy`
+depending on a package that no longer ships in this repo.
