Partially for #24457 Major changes: 1. The old `signedUserNameStringPointerKey` is quite hacky, use `ctx.Data[SignedUser]` instead 2. Move duplicate code from `Contexter` to `CommonTemplateContextData` 3. Remove incorrect copying&pasting code `ctx.Data["Err_Password"] = true` in API handlers 4. Use one unique `RenderPanicErrorPage` for panic error page rendering 5. Move `stripSlashesMiddleware` to be the first middleware 6. Install global panic recovery handler, it works for both `install` and `web` 7. Make `500.tmpl` only depend minimal template functions/variables, avoid triggering new panics Screenshot: <details> ![image](https://user-images.githubusercontent.com/2114189/235444895-cecbabb8-e7dc-4360-a31c-b982d11946a7.png) </details>
