Reference from: https://docs.swmansion.com/react-native-reanimated/examples/accordion/

Summary

Introduces a reusable Accordion with animated expand/collapse, uses it across settings, tools, activity filters, and LSPS flows, and consolidates the old form-specific wrapper into a single component via headerLayout="form". Trims unused props, adds layout shorthands, and fixes controlled accordion state in Activity Filter plus a small accessibility improvement.

What changed

Accordion component (components/Accordion.tsx)

• Animation: Height/opacity animation via Reanimated; shared open state for smooth toggling.
• headerLayout="form": Form-style accordions (KeyValue title + caret, flat/embedded body styling)
  Standard (card) accordion

How to test

• Activity → Filter → expand/collapse Services, Swaps, nested swap sections; toggles stay in sync.
• Tools → Developer Tools → category accordions open/close; layout unchanged.
• Settings / payments / channels → advanced / fee accordions; headers and carets behave as before.
• LSPS1 / LSPS7 → service info + advanced accordions.

Code Review

This pull request introduces a new reusable Accordion component with smooth animation and integrates it into ActivityFilter.tsx and DeveloperTools.tsx. The new component effectively replaces previous manual expansion/collapse logic, simplifying the UI code in consuming components. However, the Accordion component's default styling is quite opinionated, leading to extensive style overrides in its usage, which could be improved for better reusability and maintainability. Additionally, a minor detail in the animation logic could be made more robust.
