Add order-cancel debugging and multiline kbd logs

Add verbose logging + error handling for order cancellation
hotkey path and multiline style for view-mode kb msgs.

Deats,
- add `Cursor.is_hovered()` to check hover state
- log warnings when no orders cancelled via <c> hotkey
- add try-except around `.cancel_orders_under_cursor()`
- log `cur._hovered` state in `.ui._lines` hover handlers
- change `Dialog.cancel_orders()` to return `list[Dialog]`
- fix import: `Flume` from `.data.flows` vs `.data.feed`
- comment-out multi-status msgs in order submit/cancel

Also,
- convert all multiline kbd `if` conditionals to use `and`
  on separate lines for consistency
- move `import tractor` to top of `._interaction`
- change `print()` to `log.debug()` in `LevelLine`
- fix type annotation spacing: `Callable|None` vs `Callable | None`
