Unify how settings are stored

Is your feature request related to a problem? Please describe.

When editing settings in Trio subviews behave differently.

Some settings are stored and activated immediatle (I) by leaving the edit field, others need to be saved by pushing a button (B).	settings view	storing behavior
Preferences	(I)
Pump Settings	(B)**
Meal Settings	(I)
Basal Profile	(B)**
Insulin Sensitivity	(B)*
Carb Ratios	(B)*
Target Glucose	(B)*
Autotune	(B)***

• (I) is stored immediately
• * ist stored via a button labeled "Save"
• ** is stored via a button called "Save on Pump"
• *** is stored via a button called "Save as your Normal Basal Rates"

Despite that this is only a UX thing, I suggest to unify this to always have a save button. This could also be used as a hook to push the new changes to NS.

Describe the solution you'd like

1. Use the same save button everywhere
   • regardless of whether values are stored
   • only in app for "cosmetically" changes (e.g.: hours displayed on home view)
   • for basic pump behaviour (e.g. offline basal rates) or
   • for oref's needs (e.g. ISF, CR)
2. prepare a hook for pushing changes to NS with a "valid from" timestamp
3. (optional) ask for individual notes to the made changes (such as an optional commit message). Users can rethink decisions made based on their notes.

Technical Details

User Impact

• Needs the User to ALWAYS hit a save button for changes to take effect.
• Enables the user to discard changes made if not having previous values noted anywhere
• Enables storing history of changes made
