fix(mobile): use native settings and snooze controls

[juliusmarminge]

What Changed

• Use native pull-to-refresh for model discovery and a Material filter menu on Android.
• Restore grouped settings card backgrounds with platform-specific shapes.
• Give the iOS snooze popover a native navigation bar and use neutral snooze actions across platforms. Keep both date and duration pickers within the popover width.

Why

The model picker, settings groups, and custom snooze controls had drifted from native platform conventions. The handmade snooze header and filled action were especially inconsistent in dark and custom themes.

UI Changes

Settings in a custom dark theme. Before on the left, after on the right. Captured from main at 82cd1d1aabe and this branch with matching simulator, data, and scroll position.

Custom snooze in the same theme and duration mode. Before on the left, after on the right.

Android model filters after:

Native pull-to-refresh recording:

Verified on iOS 26.5 and Android 16 simulators in light, dark, and custom themes. The mobile typecheck and 18 focused tests passed. Rechecked both snooze modes after constraining the SwiftUI host width. Metro development builds are installed on Pixel 7a and iPhone 16 Pro with EAS preview environment variables.

This change is confined to the mobile client. Provider requests, shared contracts, web, and desktop are unchanged.

Checklist

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR substantially changes customer-facing mobile interactions, including native snooze navigation, model refresh behavior, Android filtering, and settings presentation across iOS and Android. The nested navigation and replacement control flows are beyond a small isolated UI adjustment and merit human review.

📝 Walkthrough

Walkthrough

The pull request standardizes mobile settings section styling, updates Android and iOS custom snooze sheet presentation, and changes thread provider catalog controls to use pull-to-refresh and an anchored Android filter menu.

Changes

Settings presentation

Layer / File(s)	Summary
Standardize settings section presentation apps/mobile/src/features/settings/components/SettingsSection.tsx, apps/mobile/src/features/settings/appearance/sections/*, apps/mobile/src/features/usage/UsageRouteScreen.tsx	SettingsSection no longer accepts card. Its non-Android container always uses card styling, and affected callers no longer pass the prop.

Custom snooze sheet

Layer / File(s)	Summary
Update custom snooze sheet presentation apps/mobile/src/features/threads/CustomSnoozeSheet.android.tsx, apps/mobile/src/features/threads/CustomSnoozeSheet.ios.tsx, apps/mobile/src/features/threads/CustomSnoozeSheet.shared.tsx	Android snooze and cancel actions use foreground-colored text buttons. iOS places the form in a native navigation container with toolbar actions and adaptive popover sizing.

Thread provider catalog controls

Layer / File(s)	Summary
Add pull-to-refresh and provider filtering apps/mobile/src/features/threads/ThreadSettingsSheet.tsx, apps/mobile/src/features/threads/provider-catalog-refresh.ts	Provider catalog refresh uses pull-to-refresh when an environment exists. Refresh errors show in an alert. Android provider filters use an anchored menu, and the iOS toolbar refresh action is removed.
