Road to No Explicit Any Part 3: Litegraph (#7935)

## Summary

- Replace `any` types with proper TypeScript types in litegraph core
files
- Focused on `LGraphCanvas.ts`, `LGraphNode.ts`, and `LGraph.ts`

## Changes

**LGraphCanvas.ts:**
- `ICreatePanelOptions` interface: `closable`, `window`, `width`,
`height`
- `options` property: `skip_events`, `viewport`, `skip_render`,
`autoresize`
- `prompt` function: `value` and `callback` parameters
- `onSearchBox` return type: `string[] | void`
- `onSearchBoxSelection` callback: `name: string`, `event: MouseEvent`
- `onDrawBackground` / `onDrawForeground` callbacks: `visible_area:
Rectangle`
- Properties Panel callback parameters

**LGraphNode.ts:**
- `onDropFile` / `onDropData`: `file: File`, `filename: string`
- `action_call` option: `string` (5 occurrences)
- `onSerialize` return type: `void`
- `onDrawTitleBar.fgcolor`: `string`

**LGraph.ts:**
- `LGraphConfig`: `align_to_grid`, `links_ontop` as `boolean`
- `triggerInput`: `value: unknown`
- `setCallback`: `func: (() => void) | undefined`
