/**
 * Fetches this employee's WhatsApp calls from the server and maps them into the same
 * CallStats.CallItem shape used for phone calls, so they can be merged into the
 * Analysis-tab detail functions (topCallerDetail, longestCallDetail, etc. — see their
 * optional `whatsappItems` param). Returns an empty list on any failure or if the app
 * isn't registered yet; callers should treat this the same as "no WhatsApp calls found"
 * rather than surfacing a separate error, matching how AnalyticsFragment's Summary tab
 * already handles this fetch.
