# Description of Changes
This pull request introduces the new "Auto Rename PDF" tool to the
frontend, enabling users to automatically rename PDF files based on
their content. The implementation includes UI components, parameter
handling, operation logic, localization, and enhancements to the file
response utilities to support backend-provided filenames. Below are the
most important changes grouped by theme:
**Feature: Auto Rename PDF Tool**
- Added the main `AutoRename` tool component (`AutoRename.tsx`) and
registered it in the tool registry, enabling selection and execution of
the auto-rename operation in the UI.

- Implemented the settings panel (`AutoRenameSettings.tsx`) and
parameter management hook (`useAutoRenameParameters.ts`), allowing users
to configure options such as using the first text as a fallback for the
filename.

- Created the operation hook (`useAutoRenameOperation.ts`) to handle API
requests, error handling, and result processing for the auto-rename
feature.
**Localization**
- Added English (US and GB) translations for the new tool, including UI
labels, descriptions, error messages, and settings.

**File Response Handling Enhancements**
- Updated the file response processor and related hooks to support
preserving backend-provided filenames via the `Content-Disposition`
header, ensuring files are renamed according to backend results.

These changes collectively deliver a new advanced tool for users to
automatically rename PDFs, with robust parameter handling, user
interface integration, and proper handling of filenames as determined by
backend logic.

# Description of Changes
Because we used string typing for IDs and names, it was really easy to
make mistakes where variables named like `subcategory` would be stored
as an ID in one file, but then read assuming it's a name in another
file. This PR changes the code to consistently use enum cases when
referring to IDs of categories, subcategories, and tools (at least in as
many places as I can find them, ~I had to add a `ToolId` enum for this
work~ I originally added a `ToolId` type for this work, but it caused
too many issues when merging with #4222 so I've pulled it back out for
now).
Making that change made it obvious where we were inconsistently passing
IDs and reading them as names etc. allowing me to fix rendering issues
in the All Tools pane, where the subcategory IDs were being rendered
directly (instead of being translated) or where IDs were being
translated into names, but were then being re-translated, causing
warnings in the log.
