Pin Send button to prevent keyboard toolbar overlap (#604)

* Pin Send button below Form to prevent keyboard toolbar overlap

Move the Send button out of the scrollable Form and pin it at the
bottom using .safeAreaInset(edge: .bottom) in all four remote command
views (TRC Bolus, TRC Meal, Loop APNS Bolus, Loop APNS Carbs).

The button is now always visible — above the keyboard when it's open,
at the bottom when it's closed. Also adds .scrollDismissesKeyboard to
allow interactive keyboard dismissal by scrolling.

Fixes #602

* Remove scrollDismissesKeyboard — keyboard has its own dismiss button
