Support real-time account switch and status update
Make a pp tracker per account and load on order mode boot. Only show details on the pp tracker for the selected account. Make the settings pane assign a `.current_pp` state on the order mode instance (for the charted symbol) on account selection switches and no longer keep a ref to a single pp tracker and allocator in the pane. `SettingsPane.update_status_ui()` now expects an explicit tracker reference as input. Still need to figure out the pnl update task logic despite the intermittent account changes.fsp_feeds
