What and why

#731 added the Steam Controller and global controller texts in English, German and Chinese. French, Italian and Swedish still showed English. This PR adds 26 keys to each of fr.json, it.json and sv.json: the global and per-game controller notes, the mapping button, the save messages and the Steam Controller section. I recomputed the list against en.json and de.json. These 26 are the only controller keys that were missing. The Steam names Steam Controller (2026), L4, L5, R4 and R5 stay as they are.

The fallback test in ControllerPreferencesTests now checks that fr, it and sv are translated. FrenchLocalizationTests lists the six Steam names that French keeps as English.

A native reader should look at fr, it and sv before the release. I am not sure about these choices:

• French: "Guide" for the Guide button (same word as English), "pavé gauche/droit" for the Steam pads, "attribution" for mapping.
• Italian: "Guide" for the Guide button, "trackpad" for the pads, "assegnazione" for mapping.
• Swedish: "Guide" for the Guide button, "platta" for the pads, "tilldelning" for mapping, "Återställ Steam Controller-styrning" for the reset button.

@zatteogit and @Dino0005 (Italian) and @Koshindai (French), you wrote earlier texts for the app. Could you read the new ones? A word for Swedish would help too.

Not part of this PR: fr.json still has no builder.* and msg.builder* keys (8), and sv.json still lacks 163 older keys (console.*, fail.*, dev.*, dep.*). They fall back to English. I can open an issue for them.

Checked

• Tests: cd frontend && swift test (766 tests, the French cognate test needed the six Steam names, fixed), cd frontend-ios && swift test, python3 tools/l10n_shell_catalogs.py --check, python3 -m unittest discover tools/tests, python3 -m unittest discover -s frontend-qt/tests.
• Test for a fix: the changed fallback test and the French cognate test above.

Screenshots

None, text only. No layout changed. Longer strings were not checked in the views.

Scope

• No engine file (dm/, scripts/, docs/, ref/) is added to the repository
• No keys, game files or data extracted from a game in the change or the attachments

Thanks @v0lumehi, the Italian reads well and matches the rest of it.json ("pulsante", "assegnazione", "Croce direzionale", "Disattivato"; "Accesso rapido", "trackpad" and "Controlli di movimento" are what Steam and Nintendo use in Italian). LGTM with two small suggestions:

• controls.steam.Guide: "Guide" is not printed on the controller, which shows the Steam logo, and Steam's Italian interface calls it "pulsante Steam". Suggest "Pulsante Steam".
• controls.gameNote: "in-game" is lost; "Condiviso con il menu dei controller nel gioco." would keep it.

Thanks @v0lumehi. I read the Italian next to the English, and most of it reads well. I agree with both of @Dino0005's suggestions, and I have three more:

Key	In the PR	Suggested
controls.mapping	Assegnazione del controller…	Assegnazione dei comandi…
controls.savingDisabled	… modificare qui l’assegnazione del suo controller.	… modificare qui l’assegnazione dei comandi.
controls.saveFailed	Impossibile salvare le modifiche. Riprova.	Non è stato possibile salvare le modifiche. Riprova.

The other texts are fine as they are.
