feat(gui): back navigation via the mouse's back button and Alt+Left

[tagawa0525]

Summary

A mouse configurator should honor the hardware it configures. This lets the device-detail screen be dismissed with the mouse's back button and with Alt+Left, and removes the Home gallery's carousel arrows/dots, which became dead controls once capture went per-device.

The back button is delivered natively while it keeps its default binding (a diverted button never reaches the OS event stream), and Alt+Left is both what a rebound button's BrowserBack action injects on Linux and what keyboard users expect. Linux has no OS-level button-8 → "back" translation (unlike Windows' WM_APPCOMMAND), so the app opts in itself, the same way browsers do.

The gallery arrows/dots only moved the selection, which no longer has a visible effect on the Home screen — the ring shows managed state and capture runs per device (#419) — so they read as dead buttons. Cards are clicked directly and the row scrolls when it overflows.

Changes

• gui: pop the device-detail screen on mouse button 4 (back) and Alt+Left (app.rs).
• gui: drop the gallery carousel arrows and dots (app/home.rs).

Testing

• cargo fmt --all -- --check / cargo clippy --workspace --all-targets -- -D warnings / cargo test --workspace — green on this branch.
• Not re-verified in the running app after the rebase onto current master. The concrete check: open a device's detail view, press the mouse's back button (button 4) or Alt+Left — the view pops back to Home; on Home the gallery shows no arrows/dots and the card row scrolls when it overflows.

Pull request overview

This PR updates the OpenLogi GUI to better match common navigation expectations in a device-centric UI: users can dismiss the device detail screen using hardware/OS “back” affordances, and the Home gallery removes carousel controls that no longer have visible effect after per-device capture.

Changes:

• Add window-level back navigation to return from device detail to Home via mouse “back” button and Alt+Left.
• Remove the Home gallery carousel arrows and indicators (dots), leaving direct card clicks and overflow scrolling as the interaction model.

crates/openlogi-gui/src/app/home.rs	Disables carousel arrows/indicators since they only affect selection, which no longer has a meaningful visual effect on Home.
