feat: show missing node packs in Errors Tab with install support (#9213)

## Summary Surfaces missing node pack information in the Errors Tab, grouped by registry pack, with one-click install support via ComfyUI Manager. ## Changes - **What**: Errors Tab now groups missing nodes by their registry pack and shows a `MissingPackGroupRow` with pack name, node/pack counts, and an Install button that triggers Manager installation. A `MissingNodeCard` shows individual unresolvable nodes that have no associated pack. `useErrorGroups` was extended to resolve missing node types to their registry packs using the `/api/workflow/missing_nodes` endpoint. `executionErrorStore` was refactored to track missing node types separately from execution errors and expose them reactively. - **Breaking**: None ## Review Focus - `useErrorGroups.ts` — the new `resolveMissingNodePacks` logic fetches pack metadata and maps node types to pack IDs; edge cases around partial resolution (some nodes have a pack, some don't) produce both `MissingPackGroupRow` and `MissingNodeCard` entries - `executionErrorStore.ts` — the store now separates `missingNodeTypes` state from `errors`; the deferred-warnings path in `app.ts` now calls `setMissingNodeTypes` so the Errors Tab is populated even when a workflow loads without executing ## Screenshots (if applicable) https://github.com/user-attachments/assets/97f8d009-0cac-4739-8740-fd3333b5a85b ┆Issue is synchronized with this [Notion page](https://www.notion.so/PR-9213-feat-show-missing-node-packs-in-Errors-Tab-with-install-support-3126d73d36508197bc4bf8ebfd2125c8) by [Unito](https://www.unito.io)
