fix(l10n): consolidate Crowdin locale files and fix ICU plural warnings

- Replace app_es-ES.arb, app_pt-PT.arb, app_tr-TR.arb (hyphen format)
  with properly named app_es_ES.arb, app_pt_PT.arb, app_tr.arb
- Fix @@locale values to match Flutter filename convention (underscore)
- Fix ICU plural syntax: remove redundant 'one {}' before '=1{...}'
  in es_ES, pt_PT, tr translations
- Regenerate l10n output files

 ## FAQ
 
+**Q: Why does the Store tab ask me to enter a URL?**  
+A: Starting from version 3.8.0, SpotiFLAC uses a decentralized extension repository system — extensions are hosted on GitHub repositories rather than a built-in server, so anyone can create and host their own. Enter a repository URL in the Store tab to browse and install extensions.
+
 **Q: Why is my download failing with "Song not found"?**  
 A: The track may not be available on the streaming services. Try enabling more download services in Settings > Download > Provider Priority, or install additional extensions like Amazon Music from the Store.

 **Q: Why is download not working in my country?**  
 A: Some countries have restricted access to certain streaming service APIs. If downloads are failing, try using a VPN to connect through a different region.
 
+**Q: Can I add SpotiFLAC to AltStore or SideStore?**
+A: Yes! You can add the official source to receive updates directly within the app. Just copy this link:
