fix(i18n): localize all remaining hardcoded aria-labels in plugin-detail components

- RecordComments: localize search/clear/pin aria-labels
- RichTextCommentInput: use nullish coalescing (??) for placeholder
- SubscriptionToggle: localize aria-label with dedicated keys
- RecordChatterPanel: localize open/close/show/hide aria-labels
- RecordActivityTimeline: localize filter/submit/loadMore aria-labels
- Add 6 new aria-label i18n keys to all 10 locale files
- Update tests to match new translated aria-label values
