Remove hardcoded guardrails from Bolus Calc settings

The pickers already have guardrails which conflict with these.

| Setting | Old StateModel Min-Max | Picker Min-Max |
| --- | --- | --- |
| Recommended Bolus Percentage | 10 - 120 % | 5 - 150 % |
| Fatty Meal Bolus Percentage | 10 - 120 % | 5 - 100 % |
| Super Bolus Percentage | 100 - 500 % | 5 - 200 % |

Note that the minimum for the `Recommended Bolus Percentage` picker drops from 50 % to 5 % in this commit.
