feat: Product page: notify when there are pending operations

[g123k]

Hi everyone!

To make users' experience less confusing, there's now a banner on the product page when there are pending edits.

Improvement 1: reduce the size of "Compatible"

The translation for "Compatible" in French was incorrect, which allowed me to implement a naive algorithm to reduce the size.

Improvement 2: product page title

Sometimes, the product name was vertically cropped on the product page (fixed ✅)

Improvement 3: picture background has a darker opacity in light mode
