Localization update

The 125 collection fish added in the last update had their descriptions written only in English. Now every one of them is described in all 23 supported languages, the same as the original 125 species.

2,875 fish descriptions, covering the full catalogue of 250 species.
Nothing else changed — no balance, no prices, no save data.

If you play in anything other than English, open any collection fish and you will see its description in your own language.
