Open WebUI 发布: v0.9.5

### Added - 🛡️ **Redirect-based SSRF protection.** All outbound HTTP requests now block 3xx redirects by default via a new `AIOHTTP_CLIENT_ALLOW_REDIRECTS` environment variable, preventing redirect-based SSRF where a public URL silently redirects to internal addresses (RFC 1918, loopback, cloud-metadata endpoints). Affected call sites include web fetch, image loading, OAuth discovery, tool server execution, and code interpreter login.
