fix(ui): exclude non-runtime strategies from switch dropdown (#175)

strategyAllowedForAccount had a loophole: runtime_enabled was only
checked when allowed_execution_modes was empty. In paper mode, strategies
with runtime_enabled=false but paper in allowed_execution_modes (e.g.
shadow_candidate, live_candidate) would pass the filter and appear in
the strategy dropdown.

Fix: check runtime_enabled first, before any mode-specific logic.
The strategy-switch-console is for live/runtime strategies only.
