OpenClaw: Windows media loaders accepted remote-host file URLs before local path validation

Summary

Windows local-media handling accepted remote-host file URLs and UNC-style paths before local-path validation, so network-hosted file targets could be treated as local content.

• src/infra/local-file-access.ts now rejects remote-host file: URLs and UNC/network paths as non-local input.
• src/media/web-media.ts, src/media-understanding/attachments.normalize.ts, and src/agents/sandbox-paths.ts all route through the shared local-file guard.

OpenClaw thanks @RacerZ-fighting, @Fushuling for reporting.
