fix(stacks): keep the stack breadcrumb trail on container attribute sub-tabs

When a container is opened from a stack, the detail tab kept the stack
trail (PR #7) but the attribute sub-tabs (Logs, Stats, Inspect, Console,
Attach) dropped it: those tabs were registered only under the global
docker.containers.container.* tree, so navigating to one left the stack
state (and its inherited params) behind, and each sub-view set a hardcoded
"Containers > ..." breadcrumb.

- Register stack-scoped child states docker.stacks.stack.container.{attach,
  exec,inspect,logs,stats} mirroring the global ones, so the inherited stack
  params survive and the trail can be kept.
- Centralize the breadcrumb logic in containerBreadcrumbs.ts (moved out of
  ItemView, which re-exports it) and add isStackContainerState +
  getContainerSubTabBreadcrumbs + buildStackContainerLinkParams.
- ActionLinksRow links sub-tabs into the stack tree (with stack+container
  params) when opened from a stack, else the global states unchanged.
- InspectView + the logs/stats/console controllers render the stack-aware
  trail; set up-front (no name) so it survives the load window and errors.

Covers regular/external/orphaned stacks and the non-stack fallback,
matching the existing ItemView breadcrumb behavior. New unit tests in
containerBreadcrumbs.test.ts.

+## Generating API types
+
+The frontend consumes a TypeScript API client (SDK functions and request/response types) that is generated from the Go API's Swagger annotations. Regenerate it after any API change — a new endpoint, a changed request/response shape, or a removed endpoint:
+
+```bash
+make generate-api
+```
+
+This runs the following pipeline:
+
+```
+Go Swagger annotations
+  → dist/docs/swagger.yaml       (make docs-build, via swaggo/swag)
+  → dist/docs/openapi.yaml       (swagger2openapi + validation)
+  → app/react/portainer/generated-api/portainer/   (hey-api/openapi-ts)
+```
+
+The generator is configured in [`openapi-ts.config.ts`](./openapi-ts.config.ts), which controls the output path, plugins, and tag filters (for example, `deprecated` endpoints and `edge_agent`-tagged routes are excluded).
+
+The generated files live in `app/react/portainer/generated-api/portainer/` and must **not** be edited by hand — your changes would be overwritten on the next run. Import the generated SDK functions and types instead of writing direct HTTP calls:
+
+- `@api/sdk.gen` — SDK functions
+- `@api/types.gen` — request/response types
+
+See [Adding api docs](./CONTRIBUTING.md#adding-api-docs) for how to annotate handlers so they are picked up by the generator.
