fix: Allow insulin delivery while loop is suspended but pump is available

[cschuijt]

In certain cases, the Insulin dialog goes yellow and only allows entering "record-only" boluses. Before 3.4.0.0/the running mode rework of loop status, these cases were limited to when there was no pump ready to run a bolus. With the rework, the condition was mistakenly changed from "is the pump suspended" to "is the loop suspended", which is why 3.4.0.0 will let you set basal rates but will not let you bolus as long as the loop is suspended. This PR restores the 3.3.2.1 behavior, reallowing boluses when the loop is suspended but the pump is available.

As the other uses for RM's isSuspended() function do intentionally look at all loop suspension reasons, I added a separate function called isPumpSuspended() and use that to determine whether pump-boluses should be allowed. This way, pump suspension/disconnection should still lead to the yellow insulin dialog, but loop suspension should let you bolus again.

Tested with Omnipod Dash, confirmed the insulin dialog shows the right version in the following cases:

• No pod active (record-only)
• Active pod, pump disconnected (record-only)
• Loop suspended (regular, on 3.4.0.0 this is record-only)
• Loop enabled (regular)
• Loop disabled (regular)

PS: this is my first time contributing to this repo, so if this is the wrong place/way to make this happen, let me know and I'll do my best to accommodate!
