* fix(CopyButton): use shadcn buttonVariants instead of duplicated variant classes

Remove hand-written variantClasses/sizeClasses that duplicated shadcn's
buttonVariants. Now extends ButtonProps and imports buttonVariants from
components/ui/button for consistent styling.

* fix(ErrorBoundary): use shadcn destructive tokens instead of hardcoded red colors

Replace hardcoded red-200/red-50/red-600 with border-destructive,
bg-destructive/5, text-destructive. Use variant='destructive' on
Button. Align error log styling with PageErrorBoundary.

* fix(TextInputArea): replace hardcoded Chinese strings with i18n t() calls

Use existing translation keys for clear success, copy success, and
copy error messages instead of hardcoded Chinese text.

* fix(QrCodePreview): use shadcn Button instead of manual button styles

Replace hand-written button class strings with shadcn Button component

Tailwind classes.

* docs(GlobalSnackbar): clarify relationship with sonner toast

Add note explaining when to use GlobalSnackbar (provider context,
severity levels, custom positioning) vs sonner toast (simple one-off
messages).

* fix(ImageUploader): wrap handleClearFile with useCallback

Prevents unnecessary re-renders by memoizing the callback, consistent
with handleFileChange which already uses useCallback.

* fix(SwitchButtonGroup): remove redundant containerPadding conditional

Both branches of the ternary returned 'p-1'. Inline the constant
directly into the className string.

* fix(TopBar): add missing openExtensionPage import

The function was called in handleOpenInTab but never imported from
utils/chromeTabs.

* fix(TopBar): add selectedIndex boundary protection in keyboard nav

Guard against out-of-bounds access when search results change during
keyboard navigation. Check selectedIndex < totalItems before accessing
arrays.

* fix(RouterContainer): remove unnecessary empty-dep useMemo

getEntryPointType() is a simple config getter. Replace useMemo(() => ..., [])
with a direct call — the empty dep array made the memo pointless.

* feat(i18n): add missing translation keys for error boundaries and copy messages

Add keys for errorBoundary, pageErrorBoundary, router, and

* fix(CopyButton): replace hardcoded Chinese strings with i18n t() calls

Use useTranslation('common') for tooltip, copy empty/success/error
toast messages.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix(ErrorBoundary): replace hardcoded Chinese with i18n via withTranslation HOC

Use react-i18next withTranslation HOC for class component to translate
title, description, and refresh button text.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix(PageErrorBoundary): replace hardcoded Chinese with i18n via withTranslation HOC

Use react-i18next withTranslation HOC for class component to translate

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
