feat: revamp tokens ui

[julia-eileen]

Acceptance Criteria

• This PR includes the revamp of the following screens:
  • See All - Tx & Blocks
  • Tokens List
  • Tokens Balance
• Since many of these screens were originally written using class component definitions, we had to duplicate the class files, adopting the naming convention NewUi<component_name>.js, as we couldn't access the feature flag hook inside them. The logic for determining which files to load is handled in the higher-level functional component.
• We made some styling adjustments on the home page to closely match the Figma design.
• The fix for the li warning on the home page is still pending. This refactor will be included in the next PR.

Security Checklist

• Ensure that no new dependencies were added unless strictly necessary, and no development dependencies were included as production ones, as this could increase the risk of dependency hijacking.
