[v3] Ensure the window name is passed as header to AssetFileServer

[jasikpark]

Description

Adds header x-wails-window-name to asset server requests, so that they can be logged.

https://github.com/jasikpark/wails/blob/eb3a7e53925d9c755afc312f1579219f8497d61f/v3/internal/assetserver/assetserver.go#L72-L80

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

I haven't tested this, but it should be possible to test by running a wails app and loading a webview window, and looking in the logs for logs like:

   dnclient-desktop: [net.defined.dnclient-desktop:go] time="2025-11-04T17:20:16-06:00" level=info msg="Asset Request:" code=200 duration="267.625µs" method=GET path=/assets/appicon-DeEhA_aB.png subsystem=ui windowID=1 windowName=

where instead, the log contains the window name:

   dnclient-desktop: [net.defined.dnclient-desktop:go] time="2025-11-04T17:20:16-06:00" level=info msg="Asset Request:" code=200 duration="267.625µs" method=GET path=/assets/appicon-DeEhA_aB.png subsystem=ui windowID=1 windowName="About"

Poem

🐰 A window name now travels through the air,
In headers dressed, so loggers see it there,
No more ID mysteries, just clarity—
One little fix, pure simplicity!

Title check	✅ Passed	The title directly describes the main change: adding the window name as a header to the AssetFileServer, which matches the core modification in application.go.
