Revert FPU guardrails

Old guardrails in Trio v0.x and this commit:
`Fat and Protein Delay`: 60 - 120
`Maximum Duration`: 5 - 12
`Spread Interval`: 10 - 60
`Fat and Protein Percentage`: 0.1 - 1.2

Guardrails in Trio-dev before this PR:
`Fat and Protein Delay`: [30] - 120
`Maximum Duration`: 5 - 12
`Spread Interval`: [5] - 60
`Fat and Protein Percentage`: 0.1 - [2]

Also:
* Update `minuteInterval` default picker value to match JSON default
* Reduce step for `Fat and Protein Delay` from `15` to `10`
* Add default values for FPU settings in `MealSettingsStateModel.swift` since they were all just 0
* Remove redundant guardrail for `Fat and Protein Percentage` in `MealSettingsStateModel.swift`
* Update verboseHint of `Fat and Protein Percentage`:
  * Remove:
    > **200% is double effect:**
    > (Fat × 180%) + (Protein x 80%)
  * Replace with:
    > **110% makes fat-to-carbs ratio essentially equal:**
    > (Fat × 99%) + (Protein x 44%)")
