feat(vscode): improve custom provider dialog layout and model toggles

[chrarnoldus]

Summary of changes

• Dialog layout & spacing: Updated CustomProviderDialog to use size="large", configured large/x-large dialog max-width and max-height constraints in packages/kilo-ui/src/components/dialog.css, and cleaned up padding so the dialog uses more viewport space.
• Advanced settings button: Replaced the plain link with an interactive secondary Button with an edit icon, making the action to edit advanced JSON settings clearly prominent and clickable.
• Bulk model capability toggles: Added "Toggle reasoning for all" and "Toggle image for all" buttons to the models section header in CustomProviderDialog with complete translations across all supported locales, allowing single-click toggling across all configured models.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Incremental review of 97d0c97 (changes since 9816009): the previous suggestion (add a Storybook story for the reworked dialog) is resolved. The new CustomProviderCreateDialog and CustomProviderEditDialog stories follow the established useDialog + onMount pattern from anaconda-desktop.stories.tsx, the mock existing data matches the ProviderConfig shape with a valid CustomProviderPackage, and StoryProviders supplies the required DialogProvider. The committed Linux baselines match the visual-regression spec's auto-discovery naming (settings--custom-provider-{create,edit}-dialog). No memory-leak surface introduced — dialog lifetime is owned by DialogProvider inside the story tree, with no timers, subscriptions, or listeners added.
