v2.5.4 — Smooth large ticket numbers (TrueType raster)

What's new

🖨 Smooth large ticket numbers

The previous large mode used ESC/POS GS ! to scale up the built-in bitmap font — which simply multiplied each dot, producing blocky/pixelated output.

v2.5.4 switches to raster image printing (GS v 0):

• Queue number is rendered with DejaVu Sans Bold TrueType font via Pillow
• Rendered at the printer's native 203 DPI — smooth, clean edges
• Auto-sizes the font to fill ~88% of the paper width
• Falls back to bitmap scaling if Pillow or the font is unavailable

Dependencies

• Added Pillow (Python image library)
• Added fonts-dejavu-core to the Docker image
