Rename Event to AppEvent and update imports

Rename the generic `Event` enum to `AppEvent` and propagate the change
through `app.rs`, `mod.rs`, and `main.rs`. Adjust function signatures,
imports, and channel usage to use the new name and the `read` helper
from crossterm. Ensure all senders/receivers now work with `AppEvent`.
