[LIE] Fix a bug in LIE#HM when matrix is disabled for the flow process

Closes #3495

based on the GREAT cell experiment simulation

More `mpirun --bind-to none`

Explicitly "free" 0-core binding of mpirun

See merge request ogs/ogs!5077

Binding to core 0 is default behaviour of mpirun(1):

Please note that mpirun automatically binds processes as of the start of the v1.8 series. Three binding patterns are used in the absence of any further directives:

Bind to core: when the number of processes is <= 2
Bind to socket: when the number of processes is > 2
Bind to none: when oversubscribed

[py] Detect runtime venv in embedded interpreter

See merge request ogs/ogs!5075

Removed hard-coded build-time venv.

[ci] Do cdash submit on failed ctest runs as well

See merge request ogs/ogs!5074

This can happen if you have the ogs-wheel installed but are running a local ogs binary. In this case use `import OpenGeoSys` or uninstall the wheel.

Parallel assembly in HM

Unfortunately with gcc-13.2.1 with optimizations there is a warning, which I was not able to correct.

former code.

inner over the process variables) of residuum names for each
process variable.

This is mostly copy from the VectorMatrixAssembler.
