refactor(1702-1): auto detect tokens component

[vinnyhoward]

Description

This PR is part of a series that breaks down the original large PR #11127 into smaller, more manageable chunks.

The AutoDetectToken functionality is valuable beyond its original implementation. By converting it into a reusable component, we can:

1. Improve code maintainability
2. Reduce duplication
3. Enhance consistency across the application and ease of use

Changes

• Extracted AutoDetectToken logic from its original location into a separate component file
• Included new tests
• Updated the original screen to use the new component
• Updated copy

Impact

This refactored component will be used in:

• Its current original screen
• New screens coming from the enhanced onboarding settings #1702 that is currently under progress

Related issues

Feature: #1702

Manual testing steps

1. On the wallet home screen check for the text "x new tokens found in this account"
2. Goto the settings page
3. Click on Advanced Settings
4. Toggle the "Auto Detect Tokens" to off
5. Check home screen to see that "x new tokens found in this account" had disappeared
6. Repeat steps 1-5 to make sure the toggle is working
