[Companion][ModelEdit] Fix/improve module custom failsafe value settings (fixes #4443): (#4492)

* Properly set limits based on model's Extended Limits setting; * Fix rounding issues between percentile display and underlying value in μs; * Add ability to display values in μs as well as percent. * Channels numbering & count is responsive to module's defined start/end channels.
