* Add success toast after saving diagram
* fix: correct save toast placement
* Changes made:
1. Added i18n support
2. Fixed the issue where the save toast was running only once
* fix: show toast after download completes, not when dialog opens
Move toast from handleDrawioSave (dialog open) to saveDiagramToFile
(after download). Also restore the duplicate-save guard that was removed.

PR #442 accidentally changed showSaveDialog from using the diagram
context to local state, breaking draw.io's native save button (Ctrl+S)
that was fixed in PR #296.
This restores the original behavior by using the context's showSaveDialog
so both draw.io native save and the download button open the same dialog.

Some models (Kimi K2, DeepSeek, Qwen text models) don't support image/vision
input. The AI SDK silently drops unsupported image parts, causing confusing
responses where the model acts as if no image was uploaded.
Added supportsImageInput() function to detect unsupported models by name,
and return a 400 error with clear guidance when users try to upload images
to these models.
