Wires up the three dialogs from build order step 5 (docs/03-gui-spec.md §§2-3) and the MainWindow slots that were declared but never implemented: - AddUrlDialog: clipboard prefill is the explicit path docs/06 R2 calls for (no passive monitoring, not advertised). - FileInfoDialog: async download.probe never blocks the UI; ends by calling download.add itself (Now / Later / Add to Queue). buildSpec() is a pure static so the optional-field-omission logic is unit-testable without touching a widget. - ProgressDialog: non-modal, WA_DeleteOnClose, driven by the taskProgress/ taskStateChanged signals RpcClient already re-broadcasts; download.get seeds state once for a dialog opened mid-transfer. Hosts SegmentBarsWidget and SpeedGraphWidget. MainWindow: openAddUrlDialog/openPropertiesForSelection/showTableContextMenu now have bodies; category.list/queue.list responses are cached so File Info can populate its category combo and queue menu without a second round trip. The row context menu covers what already exists (Resume/Pause/Stop/Delete/ Properties) and deliberately leaves out Open/Open With/Move-Rename/ Redownload/Add to Queue — those need dialogs later build-order steps haven't reached yet. util/Format.hpp: pulled the bytes/rate/eta formatting out of MainWindow and DownloadTableModel once the dialogs wanted the same strings a third time. Verified end-to-end against a running mockd (category.list/queue.list, download.probe, download.add, download.get, and live event.task.progress/ event.task.state) under ASan+UBSan: all three dialogs render correctly against real fixture data and the flow runs clean with no leaks or sanitizer reports.
