[FIX] web: fallback for domain selector operator

Before this commit, it happened that the domain selector
couldn't find the operator linked to the field.
This commit adds a fallback on the existing operators
to find an operator that matches.

for example the domain `[["name", "like", "M"]]` gave
`Name ? "M"`, now it correctly gives `Name like "M"`.

closes odoo/odoo#95891
