feat(symbols): Pass project platform to builtin symbol sources API (frontend) (#104116)

## Summary

Frontend changes to support platform-restricted builtin symbol sources.

This PR updates the Debug Files settings page to pass the project's
platform to the builtin symbol sources API endpoint, enabling
platform-based filtering of available symbol sources.

## Changes

### Frontend
- **projectDebugFiles/index.tsx**: Pass `project.platform` query
parameter to the builtin symbol sources API

## Context

This is the **frontend companion** to backend PR #102013 that adds:
- Platform restrictions for builtin symbol sources (e.g., Nintendo
Switch private servers)
- Organization-level access control via `enabledConsolePlatforms`
- Automatic default symbol sources for game engines (Unity, Unreal,
Godot)

## Implementation

The change is minimal - it adds the `platform` query parameter when
fetching builtin symbol sources:

```tsx
platform: project.platform || undefined,
```

This allows the backend to filter symbol sources based on:
1. Platform match (if source has `platforms` restriction)
2. Organization access (for platform-restricted sources)

## Deployment

**Can be merged independently** - This change is backward compatible:
- If backend doesn't have filtering yet: Parameter is ignored, no issues
- If backend has filtering: Platform-based filtering works immediately

**Related**: Backend PR #102013 (independent, can merge in any order)
