Migrate from Trillium [part 3]: Axum middleware and error handling (#2199)

Build the Axum-side middleware stack so that migrated routes (part 5+)
will behave identically to their Trillium counterparts. No routes are
migrated in this change -- all existing tests pass unchanged.

- Add `IntoResponse` impl for the `Error` enum, mirroring the Trillium
  `ErrorHandler::before_send` status-code mapping (403, 404, 406, 400,
  500).
- Add `TowerSessionStore` implementing `tower_sessions_core::SessionStore`
  against the same `session` database table (wired in part 6 when auth
  routes migrate).
- Add `axum_cors_layer()` returning a `tower_http::cors::CorsLayer`
  matching the existing Trillium CORS behavior.
- Add `ReplaceMimeTypesLayer` / `ReplaceMimeTypesService` Tower
  middleware replicating the custom MIME type negotiation (wired onto the
  API sub-router in part 7).
- Wire compression, cache-control, and CORS layers onto the Axum router
  via `ServiceBuilder`.
- Add unit tests for error response mapping and MIME type middleware.
