Describe the Bug

I updated the Brazilian Portuguese translation file to match the current English translation keys.

Branch with changes:
https://github.com/m3ryck/CrossPig/tree/feat/portuguese-translation-strings

Steps to Reproduce

1. Open the current Brazilian Portuguese translation file:
   lib/I18n/translations/portuguese.yaml

2. Compare it with:
   lib/I18n/translations/english.yaml

3. Run the i18n generator:
   python3 scripts/gen_i18n.py

Expected Behavior

Brazilian Portuguese should have the same translation keys as English, with no missing strings or fallback text.

The generated i18n report should show Portuguese with all strings translated and 0 fallbacks.

Can you rebase these changes based on the latest development branch instead

Good evening, I performed the rebase and updated with the new tags.
