Tyler Goodlet cc55e1f4bb Drop task-driven sample step graphics updates
Since moving to a "god loop" for graphics, we don't really need to have
a dedicated task for updating graphics on new sample increments. The
only UX difference will be that curves won't be updated until an actual new
rt-quote-event triggers the graphics loop -> so we'll have the chart
"jump" to a new position and new curve segments generated only when new
data arrives. This is imo fine since it's just less "idle" updates
where the chart would sit printing the same (last) value every step.
Instead only update the view increment if a new index is detected by
reading shm.

If we ever want this dedicated task update again this commit can be
easily reverted B)

Tyler Goodlet bf3b58e861 Async load data history, allow "offline" feed use
Break up real-time quote feed and history loading into 2 separate tasks
and deliver a client side `data.Feed` as soon as history is loaded
(instead of waiting for a rt quote - the previous logic). If
a symbol doesn't have history then likely the feed shouldn't be loaded
(since presumably client code will need at least "some" datums history
to do anything) and waiting on a real-time quote is dumb, since it'll
hang if the market isn't open XD. If a symbol doesn't have history we
can always write a zero/null array when we run into that case. This also
greatly speeds up feed loading when both history and quotes are available.

TL;DR summary:
- add a `_Feedsbus.start_task()` one-cancel-scope-per-task method for
  assisting with (re-)starting and stopping long running persistent
  feeds (basically a "one cancels one" style nursery API).
- add a `manage_history()` task which does all history loading (and
  eventually real-time writing) which has an independent signal and
  start it in a separate task.
- drop the "sample rate per symbol" stuff since client code doesn't really
  care when it can just inspect shm indexing/time-steps itself.
- run throttle tasks in the bus nursery thus avoiding cancelling the
  underlying sampler task on feed client disconnects.
- don't store a repeated ref the bus nursery's cancel scope..

Tyler Goodlet 7b13124dd4 Keep clear loop price pedantically up to date
To avoid the "trigger finger" issue (darks execing before they should
due to a stale last price state, normally when generating a trigger
predicate..) always iterate the loop and update the last known book
price even when no execs/triggered orders are registered.

Tyler Goodlet 71f9b5c000 Don't enable curve coord cache unless in step mode
You can get a weird "last line segment" artifact if *only* that segment
is drawn and the cache is enabled, so just disable unless in step mode
at startup and re-flash as normal when new path data is appended. Add
a `.disable_cache()` method for the multi-use in the update method. Use
line style on the `._last_line: QLineF` segment as well.
