Subject: [PATCH] perf(activity): inline FolderMan::instance() and avoid string
 concat in hot path

- FolderMan::instance(): make it an inline accessor returning the static
  pointer, removing the out-of-line call overhead at every use site
  without adding any local caching or extra complexity.
- ActivityListModel::convertLinkToActionButton: move the reply icon URL
  construction inside the isReplyIconApplicable branch and bake the
  trailing slash into the string literal so the path is a single
  immutable QString instead of two QString::operator+ allocations.
