Replaces the temporary placeholder (commented-out QuantityFormatter, raw `String(format: "%0.2f", voltage)`) with a `NumberFormatter` restoring 2 fraction digits and a `" V"` suffix. LoopUnit has no `.volt` case, so a `QuantityFormatter` (which now takes a `LoopUnit`) can't render the value. `NumberFormatter` matches the original UX (decimal style, 2 fraction digits) and goes through the locale's grouping/decimal separators -- no more raw printf. Applies to both the current-patch and previous-patch detail views; the previous-patch view goes back to calling `viewModel.batteryText` instead of formatting inline.

- MedtrumKit: pin onto loopandlearn/MedtrumKit:loop-next-dev (their fork is the canonical place for the Loop-next-dev adaptation work) plus our voltage-formatter improvement on top, pushed as a PR against loopandlearn (loopandlearn/MedtrumKit#2). - EversenseKit: replace ResizeablePicker (internal to LoopKitUI) with SwiftUI Picker(.wheel) at the 10 call sites across TransmitterSettingsView, DMSSettingsView, CalibrationView, matching the conversion loopandlearn just shipped on MedtrumKit. - LoopKit: revert the ResizeablePicker public-access change -- no external driver needs it anymore now that both MedtrumKit and EversenseKit switched to SwiftUI Picker.

Summary
Replace the temporary

.voltcase, soQuantityFormattercan't render volts. A locale-awareNumberFormatterrestores the previous UX (2 fraction digits, decimal style with locale-correct separators) without depending on a unit type we don't have.Applies to both
