Update Fonts related to BackForwardTableViewCell to use FXFontStyles

[data-sync-user]

This task is part of a series of tasks to standardizing fonts to start using FXFontStyles.

Background Context: Previously, we were using DefaultDynamicFontHelper and setting the text style, size and weight for each font, which sometimes did not match our design system. By using FXFontStyles, we can standardize our fonts and be more aligned with the design system.

Task: Please update how we set fonts in the Firefox iOS Project related:

BackForwardTableViewCell

Acceptance Criteria:

Replace usage of DefaultDynamicFontHelper with FXFontStyles

If there are discrepancies in terms of replacing the old fonts with the new standard, we will need to bring design in to approve the PR.

Please provide before and after screenshots of the UI.

Reference:

Usage example: FXFontStyles.Regular.headline.scaledFont()
