Add options for sprite generation

[cacheflush]

This PR adds some new configuration options for sprite generation:

• Minimum sprites
• Resolution of sprites
• time between two sprites

I've added the corresponding options to the system settings panel.

Sprites are now generated in a single row, to make the generation more manageable, especially for prime numbers.
I couldn't find any drawbacks to this approach since the phash generation is independent from sprite generation.

I've also added some locales using a LLM and as far as I can tell the translation is accurate.

The added documentation contains some more detailed info about the new settings.

This is related to #4023

Translations are exclusively handled via Codeberg Translate.

Scene Tagger has a button to show raw sprite which inline generation probably breaks.

If I understand this correctly, I still have to add the values to the en-GB.json manually, right?
If so I will just remove the rest from this PR.

Very good catch, I will fix this.

Yes.

I removed the unwanted locales and provided a fix to the mentioned tagger view problem.
The sprites are now generated in a dynamically sized grid.
The added functionality that comes with this PR remains untouched, while you can easily view the raw sprite in the tagger again.
