Use Lucasfont Alternate font for efficient display

[weberval]

To use the available space on the bade more efficient, I changed the font to u8g2_font_lucasfont_alternate_tf from
u8g2-fonts.

Lucasfont Alternate was created by Patrick Lauke and is licensed under CC BY 3.0. No changes to the font were made.

Summary by Sourcery

Switch default font to Lucasfont Alternate for improved screen space usage, update text rendering position, and include the u8g2-fonts dependency.

New Features:

• Switch display font to u8g2_font_lucasfont_alternate_tf for more efficient use of screen space

Enhancements:

• Adjust text baseline from y=7 to y=8 to accommodate the new font

Build:

• Add u8g2-fonts crate with embedded_graphics_textstyle feature for the new font

Reviewer's Guide

Replaces the existing 6x9 monospaced font with the compact Lucasfont Alternate via U8g2TextStyle (adjusting the text baseline), and adds the u8g2-fonts dependency.
