Fixes#8882
Adds explicit type annotations to all extension callback parameters
(`nodeCreated`, `beforeRegisterNodeDef`, `addCustomNodeDefs`) across 14
core extension files. While the types were already inferred from the
`ComfyExtension` interface, explicit annotations improve readability and
make the code self-documenting.
## Changes
- Annotate `node` parameter as `LGraphNode` in all `nodeCreated`
callbacks
- Annotate `nodeType` as `typeof LGraphNode` and `nodeData` as
`ComfyNodeDef` in all `beforeRegisterNodeDef` callbacks
- Annotate `defs` as `Record<string, ComfyNodeDef>` in
`addCustomNodeDefs`
- Add necessary type imports where missing

## Summary
This PR removes unsafe type assertions ("as unknown as Type") from test
files and improves type safety across the codebase.
### Key Changes
#### Type Safety Improvements
- Removed all instances of "as unknown as" patterns from test files
- Used proper factory functions from litegraphTestUtils instead of
custom mocks
- Made incomplete mocks explicit using Partial<T> types
- Fixed DialogStore mocking with proper interface exports
- Improved type safety with satisfies operator where applicable
#### App Parameter Removal
- **Removed the unused `app` parameter from all ComfyExtension interface
methods**
- The app parameter was always undefined at runtime as it was never
passed from invokeExtensions
- Affected methods: init, setup, addCustomNodeDefs,
beforeRegisterNodeDef, beforeRegisterVueAppNodeDefs,
registerCustomNodes, loadedGraphNode, nodeCreated, beforeConfigureGraph,
afterConfigureGraph
##### Breaking Change Analysis
Verified via Sourcegraph that this is NOT a breaking change:
- Searched all 10 affected methods across GitHub repositories
- Only one external repository
([drawthingsai/draw-things-comfyui](https://github.com/drawthingsai/draw-things-comfyui))
declares the app parameter in their extension methods
- That repository never actually uses the app parameter (just declares
it in the function signature)
- All other repositories already omit the app parameter
- Search queries used:
- [init method
search](https://sourcegraph.com/search?q=context:global+repo:%5Egithub%5C.com/.*+lang:typescript+%22init%28app%22+-repo:Comfy-Org/ComfyUI_frontend&patternType=standard)
- [setup method
search](https://sourcegraph.com/search?q=context:global+repo:%5Egithub%5C.com/.*+lang:typescript+%22setup%28app%22+-repo:Comfy-Org/ComfyUI_frontend&patternType=standard)
- Similar searches for all 10 methods confirmed no usage

### Testing
- All existing tests pass
- Type checking passes
- ESLint/oxlint checks pass
- No breaking changes for external repositories
