Fix cropped images in blog listing

[adulau]

Motivation

• The blog listing thumbnails were being clipped by the theme's fixed thumbnail height, causing banner images with different aspect ratios to appear cropped.

Description

• Override the theme's thumbnail cap in static/css/custom.css by adding rules to the #blog-listing-medium .post .image container and its img to remove the height cap (max-height: none; overflow: visible;) and ensure images scale with height: auto, object-fit: contain, and width: 100% so each banner preserves its natural aspect ratio.

Testing

• Ran git diff --check and a CSS structural assertion script to verify balanced braces and the presence of the new declarations, and attempted hugo --minify which failed because Hugo is not installed in the environment.
