Replace deprecated SheetHeader component with BottomSheetHeader from the component-library

Nobody has claimed this yet.

### **Description**

Currently, mobile is using an outdated `SheetHeader` component, which needs to be replaced with the new `BottomSheetHeader` component.

This is a massive undertaking by itself and assigning to a single contributor and creating a single PR would be too large. Smaller PRs can be submitted against this issue from multiple contributors to ensure easier review and gradual improvements.

### **Technical Details**

- Replace instances of `SheetHeader` component (`app/component-library/components/Sheet/SheetHeader/SheetHeader.tsx`) with `BottomSheetHeader` component (`app/component-library/components/BottomSheets/BottomSheetHeader/BottomSheetHeader.tsx`)
- Component APIs are slightly different so ensure all props have been migrated appropriately

### **Acceptance Criteria**

- Instances of `SheetHeader` component are completely replaced with the new `BottomSheetHeader` component
- The component APIs are updated to reflect the changes in the new `BottomSheetHeader` component and there is no functional change or visual regression
- Each Pull Request (PR) should include **no more than 3 files**
- PR descriptions must adhere to the designated template, ensuring that all relevant sections are completed including before and after screenshots of UI
- The code changes should pass Jest tests, e2e tests, linting, and Storybook without any errors

If the acceptance criteria is not met, PRs may be closed.

### **Difficulty: Intermediate**

Good first issue for: External contributors who are familiar with running mobile locally, have knowledge of React Native, component props, Jest tests, linting, and Storybook, and want to contribute to improving the cohesiveness of UI in mobile

Start by locating usages of app/component-library/components/Sheet/SheetHeader/SheetHeader.tsx and compare their props with app/component-library/components/BottomSheets/BottomSheetHeader/BottomSheetHeader.tsx. Migrate a scope of no more than 3 files, then run the relevant Jest, e2e, linting, and Storybook checks; done means no remaining SheetHeader instances and no functional or visual regression.
