Alarm consistency

[imbercal]

This PR corrects the language in alarm editor UI text to accurately reflect the underlying comparison logic. Several alarms use <= or >= comparisons but their UI text implied strict < or > comparisons, which could mislead users about exactly when alarms would trigger.

Problem

Most alarms use logic like level >= limit or level <= limit, but the UI language in .footer strings and titles often said "above" or "below" without indicating that the threshold value itself would also trigger the alarm.

For example:

• Battery alarm logic: level <= limit (fires at 20% if threshold is 20%)
• Battery alarm text: "drops below this level" (implies it wouldn't fire at exactly 20%)

Summary of Issues Found

Alarm	Component	Previous Text	Logic	Mismatch
Phone Battery	Footer	"drops below"	<=	Missing "or equal to"
Pump Battery	Footer	"drops below"	<=	Missing "or equal to"
COB	InfoBanner	"exceeds"	>=	"exceeds" implies > not >=
COB	Footer	"is above"	>=	Missing "or equal to"
RecBolus	Footer	"is above"	>=	Missing "or equal to"
RecBolus	Title	"More than"	>=	"More than" implies > not >=
MissedBolus (carbs)	Footer	"below"	ignores <=	Missing "or equal to"
MissedBolus (bolus)	Footer	"below"	ignores <=	Missing "or equal to"

Changes

PhoneBatteryAlarmEditor.swift

• Footer: "drops below" → "drops to or below"

PumpBatteryAlarmEditor.swift

• Footer: "drops below" → "drops to or below"

COBAlarmEditor.swift

• InfoBanner: "exceeds" → "reaches or exceeds"
• Footer: "is above" → "is at or above"
• Title: "Above" → "At or Above"

RecBolusAlarmEditor.swift

• Footer: "is above" → "is at or above"
• Title: "More than" → "At or Above"

MissedBolusAlarmEditor.swift

• Ignore small boluses footer: "below" → "at or below"
• Ignore small boluses title: "Ignore below" → "Ignore at or below"
• Ignore small carbs footer: "below" → "at or below"
• Ignore small carbs title: "Below" → "At or Below"

Logic Reference

Alarm	Condition File	Logic	Now Matches UI
Phone Battery	PhoneBatteryCondition.swift	level <= limit	"to or below"
Pump Battery	PumpBatteryCondition.swift	level <= limit	"to or below"
COB	COBCondition.swift:12	cob >= threshold	"at or above"
RecBolus	RecBolusCondition.swift:16	rec >= threshold	"at or above"
MissedBolus (carbs)	MissedBolusCondition.swift:37	carb.grams > minCarbGr (ignores <=)	"at or below"
MissedBolus (bolus)	MissedBolusCondition.swift:55	bolus.units > minBolusU (ignores <=)	"at or below"

Not Changed

The MissedBolus "Ignore low BG" section was already correct:

• Footer: "Only alert if the current BG is above this value."
• Logic: Fires when BG > threshold (strict greater than)

Testing

1. Open each alarm editor and verify the updated text displays correctly:
   • Settings → Alarms → [Add or edit each alarm type]
   • Low Battery (Phone)
   • Low Battery (Pump)
   • COB Alert
   • Rec. Bolus
   • Missed Bolus Alert

Note - no logic has been changed (so there are all 4 options, >, <, >=, <=) - whether it should be standardised so all alarms are >= or <= and the text updated to reflect that?
