fix(translations): actualize the translations from all pages in the web

[NorbertAguilera]

📝 Description (User Story)

As a Content Manager / Product Owner,
I want to update and synchronize the translations across all pages of the web application,
So that international users receive accurate, up-to-date, and localized information.

🔗 Epic / Parent Issue

Part of: #ID_PADRE

✅ Acceptance Criteria (Fit Criteria)

• All missing translation keys across all web pages are identified and populated.
• Language switching works seamlessly on every page without breaking the UI or layouts.
• Fallback mechanisms work correctly (if a translation is missing in one language, it defaults to the primary language).

🛠️ Technical Checkpoints / Tasks

• Pull latest translation strings/copy from the translation management tool (e.g., Crowdin, Phrase, or Excel sheets).
• Update locale/translation files in the codebase (Backend/Frontend localized dictionaries).
• Check for hardcoded strings in components and extract them to translation keys.
• Test edge cases, such as long text strings in specific languages (e.g., German) to ensure the layout doesn't break.
