layouts - Updated 6 premium feature layout files to use @string and @dimen resources: * bottom_sheet_chat_history.xml * item_chat_history.xml * dialog_document_upload.xml * dialog_chat_export.xml * panel_tutoring_mode.xml * activity_chat.xml - Updated existing layouts (activity_grammar.xml, item_grammar_correction.xml) - Created comprehensive XML drawable resources: * 13 vector drawable icons (stars, file, send, arrow, more) * Button backgrounds with ripple effects * Shape drawables for cards and dividers - Expanded strings.xml with 140+ entries for all premium features - Expanded dimens.xml with 70+ dimension definitions - All hardcoded strings and dimensions now use resource references - Improved localization and design consistency ---
