fix(api-keys): reuse shared copy button for created keys

[stemirkhan]

Summary

• replace the custom inline copy logic in the API key created dialog with the shared CopyButton
• reuse the existing clipboard success/error handling instead of calling navigator.clipboard.writeText(...) directly
• add focused component coverage for copying a newly created API key

Why

The API key created dialog had its own minimal clipboard implementation with no error handling or user feedback on failure. Reusing the shared copy control makes the behavior consistent across browsers and aligns this dialog with the rest of the frontend.

Testing

• cd frontend && npx -y node@20 ./node_modules/vitest/vitest.mjs run src/components/copy-button.test.tsx src/features/api-keys/components/api-key-created-dialog.test.tsx

Notes

• fixes не копируется api ключ #389
• related to Copy on newly created API key not working (Windows, Edge and Vivaldi) #127

Clean refactor replacing the inline clipboard logic with the shared CopyButton component. Approving.

• Shared CopyButton already has error handling (toast.error("Failed to copy")) which the previous inline version was missing — this is the user-facing improvement behind #127.
• Removes 36 lines of duplicated component code and drops 2 lucide imports.
• Frontend-only, no collisions with recently merged #421.
• CI 18/18 green.

Merging into the v1.13.2 batch.
