Some strings are missing from Crowdin and some translated strings still appear in English

[teogabrielofc]

Bug Description

Some strings that exist in the app are not present in the app_en.arb file, so they never show up on Crowdin for translation. For example, "Playback Speed" appears in the app but cannot be found in the .arb file or on Crowdin.
Additionally, some strings that are already translated on Crowdin still appear in English in the app.

Steps to Reproduce

1. Open Musly
2. Change the language to any translated language other than English
3. Play any song
4. Notice that some strings like "Playing From" and "Playing Next" still appear in English even though they are already translated on Crowdin, and "Playback Speed" doesn't exist on Crowdin at all

Expected Behavior

All visible strings in the app should be present in the .arb file and available for translation on Crowdin. Already translated strings should appear in the correct language.
