Coveralls fixes (#2361)

## Problem

- The Coveralls reporting step in the GitHub Actions got stuck ([example
job](https://github.com/agama-project/agama/actions/runs/15013186385/job/42185530706#step:9:170))
- And because the default timeout is 6 hours then the CI was stuck for 6
hours
- The number of the assigned Action runners is limited so after reaching
the limit new CI actions were not started and were waiting until some
previous job is finished.

## Debugging

- At first I noticed an error in the Coveralls output:
`⚠️ git log -1 --pretty=format:'%H%n%aN%n%aE%n%cN%n%cE%n%s' (return code
128)`
see
https://github.com/agama-project/agama/actions/runs/15023225072/job/42217441468#step:14:166
- Running this command in a separate step showed that it was failing
because of a different file owner:
`fatal: detected dubious ownership in repository at '/__w/agama/agama'`
see
https://github.com/agama-project/agama/actions/runs/15020310724/job/42207691974#step:9:9
- But even after adding that config command it got still stuck
- After enabling the Coveralls steps in the web frontend again I noticed
that it works fine without any problem so I tested moving the Coveralls
step outside the container and it worked.
- Very likely there is some incompatibility in the Coveralls action and
it does not work well when running inside a container with openSUSE
Tumbleweed (Different `git` CLI tool? Different glibc, nodejs or
something else?)

## Solution

- Enable back the code coverage reporting in the web frontend
- Configure `git` so a different owner is OK (this was not the root of
the problem in the end but this could cause troubles elsewhere later so
I'm keeping this change anyway.)
- Run the coverage actions outside container, run them in the Ubuntu
host directly
(That's a bit tricky, if a job runs in a container then all steps run in
the container, you cannot run a command outside the container. The
workaround is to define a dependent job which runs outside the conta... (continued)
