Enlarge BG text and add optional display name

[bjorkert]

This PR introduces several enhancements to the Snoozer view to improve at-a-glance readability and provide better user context, addressing Issue #440 .

Key Changes:

• Larger BG Text: The font size and frame for the BG value have been increased, making it the primary focal point of the view.
• Optional Display Name: The app's display name can now be shown in the rightColumn, which works well in both portrait and landscape modes. This is controlled by the showDisplayName setting.
• Adaptive Landscape Layout: In landscape mode, the trend arrow and delta value are now displayed side-by-side for a more compact and readable layout.

Summary

Overall - works as coded.
Questions

• seems like the name on snoozer should be in bigger font too (I'd make the name bigger than the emoji) and in portrait maybe above the glucose
• we decided not to do this one: I think the default for a new instance (not a rebuild) of LoopFollow should configure the name to be enabled

Test

Looks good. These results were with LoopFollow, General Settings, Show Display Name enabled. After I captured the screenshots, I enabled Snoozer emoji too - I like that. (I know you added it a while ago.) Snoozer screen still good with emoji and name both enabled.

Landscape with dev (upper) and with PR (lower):

I reviewed the code and tested. I remarked on some possible modifications. But I approve as is if you decide not to include these suggestions.

Updated the display name presentation in SnoozerView:

• Increased font size from ~22pt to 50pt bold for better visibility
• In portrait mode: Display name now appears above the glucose value (handled by leftColumn)
• In landscape mode: Display name remains in the right column with the larger font
