Pass display state table to interaction handlers 

This took a teensie bit of reworking in some `.ui` modules
more or less in the following order of functional dependence:

- add a `Ctl-R` kb-binding to trigger a `Viz.reset_graphics()` in
  the kb-handler task `handle_viewmode_kb_inputs()`.
  - call the new method on all `Viz`s (& for all sample-rates) and
    `DisplayState` refs provided in a (new input)
    `dss: dict[str, DisplayState]` table, which was originally inite-ed
    from the multi-feed display loop (so orig in `.graphics_update_loop()`
    but now provided as an input to that func, see below..)
- `._interaction`: allow binding in `async_handler()` kwargs (`via
  a `functools.partial`) passed to `ChartView.open_async_input_handler()`
  such that arbitrary inputs to our kb+mouse handler funcs can accept
  "wtv we desire".
  - use ^ to bind in the aforementioned `dss` display-state table to
    said handlers!
- define the `dss` table (as mentioned) inside `._display.display_symbol_data()`
  and pass it into the update loop funcs as well as the newly augmented
  `.open_async_input_handler()` calls,
  - drop calling `chart.view.open_async_input_handler()` from the
    `.order_mode.open_order_mode()`'s enter block and instead factor it
    into the caller to support passing the `dss` table to the kb
    handlers.
  - comment out the original history update loop handling of forced `Viz`
    redraws entirely since we now have a manual method via `Ctl-R`.
  - now, just update the `._remote_ctl.dss: dict` with this table since
    we want to also provide rc for **all** loaded feeds, not just the
    currently shown one/set.
- docs, naming and typing tweaks to `._event.open_handlers()`
