fix(dash): only act on key Press events in the overlay dispatch (#89)

The dash event loop dispatched each operational overlay (serve wizard,
engine manager, onboarding, …) straight to its `on_key` via
`if state.<overlay>.is_some()` arms that ran BEFORE the general
`handle_key` — the only place filtering non-Press key events. Terminals
that also emit Release/Repeat events (Windows Terminal / ConPTY under
WSL, kitty keyboard protocol) thus delivered each keystroke to overlays
twice.

For the serve wizard's model picker this meant Enter chose+closed the
picker on Press, then the Release/Repeat echo re-opened it seeded with
the just-chosen model as a filter — so the model could never be selected.
This hit both the bare-`rocm` launcher (focused Serve) and the full dash,
since both share this loop.

Extract `is_actionable_key(KeyEventKind)` (Press only), add a
top-priority arm that swallows non-Press key events above every key arm
so the Press-only invariant covers overlays too, and route `handle_key`
through the same predicate. Regression test:
`only_press_key_events_are_actionable`.
