no coveralls

[penelopeysm]

For some reason we have two coverage providers, codecov and coveralls.

Coveralls is prone to failing during CI because sometimes its servers are down, or other weird bugs that I've tried to figure out once, but couldn't.

This was discussed at one of the team's Monday meetings (29/9/25) and nobody knew why we had two providers.

This PR therefore removes coveralls (but keeps codecov).
