### UPD: Feat: Add Validators & Error Toast for Mermaid & Vega diagrams
Description:
As many time the diagrams generated or entered have syntax errors the diagrams are not rendered due to that errors, but as there isn't any notification is difficult to know what happend.
This PR add validator and toast notification when error on Mermaid and Vega/Vega-Lite diagrams, helping the user to fix its.
Note:
Another possibility of integrating this Graph Visualizer is through its svelte component: https://github.com/vega/svelte-vega/tree/main/packages/svelte-vega

### FEAT: Add Vega Char Visualizer Renderer
Add suport for Vega-Lite Specifications.
Vega-Lite is a "compiled" version of Vega Char Visualizer.
For be rendered with Vega it have to be compiled.
This PR add the check and compile if necessary, is a complement of recent Vega Renderer Feature added.
### FEAT: Add Vega Char Visualizer Renderer
Feature required in https://github.com/open-webui/open-webui/discussions/18022
Added npm vega lib to package.json
Added function for visualization renderer to src/libs/utils/index.ts
Added logic to src/lib/components/chat/Messages/CodeBlock.svelte
The treatment is similar as for mermaid diagrams.

This commit introduces the necessary logic and UI controls to allow users to switch the Flow component layout between vertical and horizontal orientations.
* **`Flow.svelte` Refactoring:**
* Updates logic for calculating level offsets and node positions to consistently respect the current flow orientation.
* Adds a control panel using `<Controls>` and `<SwitchButton>` components.
* Provides user interface elements to easily switch the flow layout between horizontal and vertical orientations.
This refactors the model import functionality to improve performance and user experience by centralizing the logic on the backend.
Previously, the frontend would parse an imported JSON file and send an individual API request for each model, which was slow and inefficient.
This change introduces a new backend endpoint, `/api/v1/models/import`, that accepts a list of model objects. The frontend now reads the selected JSON file, parses it, and sends the entire payload to the backend in a single request. The backend then processes this list, creating or updating models as necessary.
This commit also includes the following fixes:
- Handles cases where the imported JSON contains models without `meta` or `params` fields by providing default empty values.
This moves the JSON model import functionality to the backend. Instead of the frontend parsing the JSON file and sending multiple requests, it now uploads the file to a new endpoint (/api/v1/models/import), which processes the file and imports the models. This improves efficiency and provides better user feedback.
The previous implementation for unarchiving all chats in `ArchivedChatsModal.svelte` was inefficient, as it sent a separate request for each chat, which could potentially overload the server.
This commit introduces a new backend endpoint, `/chats/unarchive/all`, to handle the bulk unarchiving of all chats for a user with a single API call.
The frontend has been updated to use this new endpoint, resolving the performance issue by minimizing the number of requests to the server.
This commit introduces a new setting in the Interface settings that allows users to control whether the chat title is used as the browser's tab title.
The following changes were made:
- Added `useChatTitleAsTabTitle` to the `Settings` type in `src/lib/stores/index.ts`.
- Added a toggle switch in `src/lib/components/chat/Settings/Interface.svelte` to manage this new setting.
- Updated `src/lib/components/chat/Chat.svelte` to conditionally set the document title based on the `useChatTitleAsTabTitle` setting.
This change introduces a visual warning in the group settings page. The warning appears when an admin attempts to disable a permission for a group that is already enabled in the default 'user' group. This is necessary because permissions are additive, and disabling a permission in a specific group will not revoke it if it's enabled in the default group.
To achieve this, the following changes were made:
- A new `PermissionSwitch.svelte` component was created to encapsulate the permission switch and its warning logic, avoiding redundant code.
- The `Groups.svelte` component was updated to correctly fetch the default user group's permissions.
- The `Permissions.svelte` component was refactored to use the new `PermissionSwitch.svelte` component, making the code cleaner and more maintainable.
