Fix Cmd+R keyboard shortcut when dialogs are open

[Copilot]

Cmd+R (reset viewport) was non-functional when AlertDialog components were open because modal dialogs capture keyboard focus, preventing event propagation to the app root handler.

Changes

• FileDetailsDialog & PrDetailsDialog: Added onPreviewKeyEvent modifier to intercept Cmd+R and call onResetViewport()
• DialogHost: Added onResetViewport parameter and threaded it through to child dialogs
• App: Wired vm.resetViewport() callback to dialog hierarchy

Implementation

@OptIn(ExperimentalComposeUiApi::class)
AlertDialog(
    onDismissRequest = onDismiss,
    modifier = Modifier.onPreviewKeyEvent { event ->
        if (event.type == KeyEventType.KeyDown && event.isMetaPressed && event.key == Key.R) {
            onResetViewport()
            true
        } else {
            false
        }
    },
    // ...
)

Pattern matches existing keyboard handler in App.kt lines 203-207.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
