translation fixes for v1.3.0

[SanderDevisscher]

♦️ : breaking issue
🟠 : notable issue
🟡 : Nice to haves
👋 : we'll fix this
👉 : can you fix this?
🤝 : we need to work together on this

Checklist indicators:

• 🟡🤝: There is no text in the 2nd level pathways filter. Is this due to some missing translations ?
• 🟡👋: allnativeranges is missing a translation => "All native ranges"
• 🟡👋: allPathwaySubCategories is missing a translation
• 🟡👋: missingFilters_species is missing a translation (warning message that either the Species dropdown or the Region dropdown at the top of the "species information" tab is empty)

FAQ:

• 🟡👋: Expand "Export graphs" section to include option to download graph using "download graph" button.

Species indicators:

• 🟠👉: The "k" in the popups on the management graphs below the map when values exceed 1000 should be omitted. This is confusing since it says 1.000k to indicate 1.000 instead of 1.000.000 which it implies
• 🟠🤝: Currently it is unclear what the unit is in observations graphs. If I'm not mistaken it's the "occupancy of 1x1km squares"
  • 🟠👉: Can you add "Occupancy (no. 1x1km squares)" as x-axis label (modifiable)
  • 🟠👋: Rename "Observations" tab to "Occupancy"
  • 🟠👋: Rework observations description

Report:

• 🟠👉: The GAM graphs lose their color scheme in the report this makes the description incorrect. Can you check if the color scheme can be maintained ?
• 🟠👉: In the report the Management graph misses it's unit on the x-axis (ea "catch per unit of effort")
• 🟡👉: Information under "More" is missing from the the report. It would be nice to include this into the report but not priority. => moved to next milestone as [Enhancement] add "more" to report alien-species-portal#204

@SaarJunius I can't seem to find the entries for allnativeranges, allPathwaySubCategories & missingFilters_species in translation_simple.csv. Are they listed in another file ? are they hardcoded ? are they named differently?

@SaarJunius I also can't find the entry for downloadGraph. Currently its 'download graph' in all languages

Those entries were indeed not yet added to the translation_simple.csv. I will create a dummy entry for them that you can fill in.

This one is currently hardcoded in the data (similar to the "Download data" button, where the text is also hard-coded). Do you want me to make them both adaptable?

EDIT: I've added the missing entries in this commit 25fe1e0 (in the branch where you also made the other changes for this issue)
