Today I checked the electrician’s work. In one spot where 7x1.5mm² (around 8 AWG) cables were supposed to be installed, instead 5x1.5mm² + 3x1.5mm² cables were laid. However, this would mean I’m missing one live conductor. Or is it allowed to use the "second neutral conductor" of the 3x1.5mm² cable as a live conductor?

Green/yellow is definitely designated for earth/PE by law.
Blue is considered a neutral conductor and is nice to have, but it can also be used as a switched live or similar.
So what your electrician is doing is absolutely fine.
At least, that was the case during my apprenticeship (8 years ago).

Unfortunately, I also couldn’t find anything about this on Google.
The use of conductor colors is specified in standards [2] and [3]. Both regulations contain the following, essentially consistent statements:
• If a circuit includes a neutral conductor identified by color, the conductor must be blue or light blue.
• If no neutral conductor is required, the blue conductor may be used for any other purpose except as a protective conductor.
• If a circuit includes a neutral conductor identified by color, the conductor must be blue or light blue.
• If no neutral conductor is required, the blue conductor may be used for any other purpose except as a protective conductor.
