What is this PR

• Bug fix
• Addition of a new feature
• Other

Adds documentation and a blog post for the new allen_mouse_momap_10um atlas (Falasconi, Kanodia et al., 2026, Cell). The atlas uses the Allen CCFv3 P56 STPT template at 10 µm and splits the motor cortex into 16 modules (MO1–16) based on where they project, on top of the full CCFv3 annotations.

Changes:

• Atlas table (_atlas_table.md): adds a row for the atlas, with a "More info" badge.
• Atlas details (usage/atlas-details.md): adds a new section at the end of ## Mouse with a description, the atlas name and a Neuroglancer link.
• Blog post (blog/momap-added.md): announces the atlas, briefly describes the method, and explains how to install and view it.
• Images (blog/images/): momap_modules.png and momap_coronal.gif.
