epic: Sleepypod Mini — iOS device switcher + Mini screens

[ng]

Vision

Add Mini (Snoo bassinet) support to the iOS app via a device switcher in the gear menu. Pod UI stays untouched. Mini gets purpose-built screens (~3-4 new views vs pod's ~30).

Device Switcher

• Gear menu at top → Pod | Mini toggle
• Each device type has its own tab set and view hierarchy
• SleepypodProtocol abstraction already exists — add MiniClient conforming to a new MiniProtocol
• Discover available servers on network (pod server advertises which device types are enabled)

Mini Tab Structure

• Control — current state, motion level dial (1-4), on/off, lock toggle
• Sleep Log — session history, duration charts, soothe event timeline
• Settings — sound type, volume, weaning mode, device info

Baby Biometrics

• Sleep duration trends (daily/weekly bar charts, reuse WeeklyBarChartView)
• Cry frequency from soothe escalation data
• Soothe responsiveness patterns
• These could be a tab or integrated into Sleep Log

Architecture

• MiniClient — talks to sleepypod-core Mini tRPC routes
• MiniDeviceManager — manages connection, state, polling
• Mini views in Views/Mini/ directory
• Shared infrastructure: Theme, networking, settings, notifications

Naming

• Device type in UI: "Mini"
• Code: Mini prefix (MiniClient, MiniScreen, etc.)
• No Snoo trademark usage anywhere in UI or marketing
