feat: dreport-service + dreport-ffi + nuget packages

Extract orchestration (font registry + render pipeline) from the Axum
backend into a standalone dreport-service crate. Backend becomes a thin
HTTP adapter on top.

Add dreport-ffi (cdylib) exposing the service through a stable C ABI
with opaque handles, byte buffers, and thread-local error reporting.

Build Dreport.Service + Dreport.AspNetCore NuGet packages under
bindings/dotnet/, packing the host RID native binary via a generated
nuspec. justfile recipes (nuget-publish, nuget-publish-all) build,
pack, and push to the Gitea NuGet registry in one shot.

Test coverage: 47 Rust + 38 C# (xUnit + WebApplicationFactory).

+//!
+//! ## Conventions
+//!
+//! - All exported symbols are prefixed `dreport_`.
+//! - Functions return `i32`: `0 == success`, negative values are error codes.
+//!   See [`error_code`] constants. The detailed message for the most recent
+//!   error on the calling thread is retrievable via [`dreport_last_error`].
+//! - Outbound dynamic data is returned as a [`DreportBuffer`] (ptr + len + cap).
+//!   The caller MUST hand the buffer back to [`dreport_buffer_free`] to release it.
