Changes

#21 - Add creator card follower count pill

Created FollowerCountPill.tsx - a compact pill rendering a follower count with K/M abbreviations. Returns null for missing or negative values so creator cards degrade cleanly.

#22 - Add creator profile back button header

Created BackHeader.tsx - renders a back button (calls navigate(-1) or an optional onBack override) beside a title and optional subtitle. Responsive with truncate on long strings.

#23 - Add truncated wallet address display component

Created TruncatedAddress.tsx - truncates long addresses to prefix...suffix format with configurable char counts. Includes an optional copy button that resets after 2 seconds.
