When an application doesn't show up in the application picker, or a remap for it doesn't apply, there was no way to see what the desktop actually reports. This adds a window list that shows xremap's raw answer, and gathers the troubleshooting tools out of everyday sight in the ⋯ menu.

Window list

• Opens in its own window, like the remapping log, and lists every window exactly as xremap --list-windows prints it: the application id that application-specific remaps match on, and the title.
• Asks the same xremap binary the service uses (its path is shown) every 5 seconds while the window is open, and stops when it closes. --list-windows exits before xremap touches any input device.
• Nothing is merged or left out: Keyloom's own windows, every window of an application, and windows without an id (shown as "none") all appear.
• Ids and titles are selectable (drag, double- or triple-click, Ctrl+C, and right-click Copy / Select All through libcosmic's selectable_text). Copy puts every row on the clipboard as tab-separated id and title.
• When xremap is missing or can't ask the desktop, the window shows xremap's own explanation and keeps trying.

Troubleshooting menu

• The ⋯ menu now ends with a muted, collapsed Troubleshooting ▸ entry holding the remapping log, the window list, and "Reset all mappings". It starts collapsed every time the menu opens.
• The "Show log" button on failure toasts is unchanged. Without systemd there's no log entry, and the Tester page leaves out the reset entry.

Internals

• apps::parse_window_list now keeps every row. The picker's de-duplication and filtering moved into apps::applications, so the picker behaves as before.
• The log window's frame and window settings moved to shared helpers (ui::side_window, ui::side_window_settings) so both side windows look identical.

Docs

docs/Current_Features.md gains a "Window list" section and says where the log and reset now live.

Validation

• cargo fmt --all -- --check, cargo clippy --all-targets --all-features --locked -- -D warnings: clean
• cargo test --verbose --locked: 335 passed, 21 ignored
• New tests cover parsing every row, the copied text, opening and closing the window list, its rows and error banner, and the Troubleshooting entry staying collapsed until asked for.
• Checked in headless renders at the default and smallest window sizes.

Not verified on a live desktop: the 5-second refresh against a real compositor, and the right-click menu, which libcosmic shows as a popup on Wayland and an overlay on X11. Both are worth a quick look on COSMIC and on one other desktop.
