* fix(runtime): use internal path for HandlePlatformFileDrop
The Go backend was calling window.wails.Window.HandlePlatformFileDrop()
for native file drops on macOS/Linux. This only worked with the bundled
runtime which sets window.wails = Runtime.
When using the @wailsio/runtime npm module, window.wails is an empty
object because the npm module only exports via ES modules and registers
the handler at window._wails.handlePlatformFileDrop.
Changed the Go code to call the internal path that both runtime
distributions set up: window._wails.handlePlatformFileDrop()
Also added a test case that uses the npm module to verify the fix.
