• use primary text color
• for "Message Request" and "Group Request" panels don't use inset glass panel
background as double insets use too much screen estate.
• modernize and unify appearance of different conversation input blocking panels.
• make chat search bar look pretty on iOS 26.
• add blur/tint under the conversation input bottom bar to improve legibility.
