One frame for every window (frame.rs): command dialogs dock right and shrink to their content (260 to 380 px, 560 for table dialogs), floating windows are centred and capped (460 px, 760 for tables); header and footer rows right-align without stretching the dialog, long texts wrap; all windows migrated; tests: no egui::Window outside frame.rs, every command's dialog and the floating windows measured within limits
