📝 feat(SettingsAnnouncements/SettingsFAQ): update placeholders & success texts, add Markdown/HTML hint

• SettingsAnnouncements.js
  – Placeholder now states “Supports Markdown/HTML” for both small & expanded editors
  – Success/alert messages unified to use Chinese quotation marks

• SettingsFAQ.js
  – Answer textarea placeholder updated with Markdown/HTML support note
  – Unified success/alert messages punctuation

These tweaks clarify rich-text support and keep UI copy consistent.
