feat(app): Settings reorder + plan card A/B (settings-plan-card) (stacked on #21711)

[YinkaAdepoju]

Stacked on #21711. This branch starts from #21711's head, so until that merges the diff below includes it. The Settings commits are 16342d0 through 1c40413.

Summary

Settings now puts the places people open most at the top.

• Device, Recording & Transcription, Notifications & Display and Data & Privacy (most visits to Settings) now sit right under Account and Plan & Usage.
• Voice, Integrations and Connect an Agent come next. Memories and Goals keep their own group.
• Referral Program moves next to Help & About and Feedback, and drops the green NEW tag.
• The Device row shows the device's battery, or Connected / Disconnected, so you can check it without opening the page.
• Plan card for Free and Plus, behind an A/B test (see below): a card with a small Plan & Usage label, the plan name large, the minutes meter and a full-width Upgrade. Tapping the card outside Upgrade opens Plan & Usage; paid plans keep the plain row.
• No handle band at the top of the Settings sheet: the header (with the close X) is the top, and the sheet still swipes down to close. app/docs/ux-contract.md notes the exception.
• The Account row shows the person's initial instead of a generic person icon.

Nothing moved deeper: every row is still on the sheet or one tap below it (settings_structure_test).

Screenshots

Before	After

Before: widget-test render of #21711's head (Free plan). After: iOS simulator, card arm, local test account on Free, no device connected.

A/B test: settings-plan-card

• PostHog flag settings-plan-card, draft experiment 486057 (not launched; launch once this build is in the stores). 50/50 control / card, split by user.
• control: the Plan & Usage row with the minutes meter and a full-width Upgrade under it (feat(app): redesigned Home behind the home-redesign A/B flag (recording pill, upgrade in place) #21711's layout). card: the plan card above.
• Exposure: $feature_flag_called when the section is drawn for a Free or Plus reader with a PostHog-assigned arm. No identity, an unread flag or an unknown variant shows control and is not counted.
• Primary metric: Upgrade Succeeded within 7 days of exposure. Secondary: Upgrade Plan Selected; guardrail: Product Error per user.
• Pre-registration: product/experiments/settings-plan-card.md; flag added to config/feature-flags.yaml.
• Debug builds: --dart-define=OMI_SETTINGS_PLAN_CARD=control|card.
• The reorder, Device status and Account initial ship to everyone (findability, not conversion).

Testing

• flutter test test/widgets/settings test/spine/b1_settings_surface_test.dart test/widgets/semantics_baseline_test.dart test/unit/appearance_test.dart: 55 pass (settings, B1 surface spine, semantics baseline), including both experiment arms, the fallback-is-not-counted rule and the exposure key.
• settings_structure_test checks the new order and that the Device row shows the battery; settings_plan_section_test checks the card replaces the row on Free and Plus and that tapping it opens Plan & Usage.
• Checked on the iOS simulator (iPhone 17 Pro, iOS 26.5).

Line-count exceptions

Line-Count-Exception: app/lib/backend/preferences.dart | 1538 -> 1543 | one setting: the closed "Teach Omi your voice" card
Line-Count-Exception: app/lib/pages/settings/transcription_settings_page.dart | 1572 -> 1575 | upgrade opens the paywall in place instead of the Usage page
Line-Count-Exception: app/lib/providers/device_provider.dart | 1598 -> 1614 | a firmware prompt found during onboarding waits until Home is up
Line-Count-Exception: app/lib/utils/analytics/analytics_manager.dart | 3113 -> 3120 | paywall re-ask events

(These four come from #21711, which this branch includes until it merges.)

Product invariants affected

• INV-MEM-1: no change to how memories are stored or reviewed (from feat(app): redesigned Home behind the home-redesign A/B flag (recording pill, upgrade in place) #21711; this commit only reorders Settings rows).

Closing in favour of #21763, which has the same Settings changes rebuilt directly on main (no longer stacked on #21711), plus the plan card A/B test.

Hey @YinkaAdepoju 👋

Thank you so much for taking the time to contribute to Omi! We truly appreciate you putting in the effort to submit this pull request.

After careful review, we've decided not to merge this particular PR. Please don't take this personally — we genuinely try to merge as many contributions as possible, but sometimes we have to make tough calls based on:

• Project standards — Ensuring consistency across the codebase
• User needs — Making sure changes align with what our users need
• Code best practices — Maintaining code quality and maintainability
• Project direction — Keeping aligned with our product principles and locked invariants

Before your next PR, please skim:

• PRODUCT.md — product north star
• Product invariants — locked rules (shared chat, memory tiers, agent control plane, integrations, brand)

If this was declined for direction or taste, maintainers should cite an invariant ID or open a proposed one — ask if that citation is missing.

Your contribution is still valuable to us, and we'd love to see you contribute again in the future! If you'd like feedback on how to improve this PR or want to discuss alternative approaches, please don't hesitate to reach out.

Thank you for being part of the Omi community!
