📝 Summary of changes done and why they are done

This PR fixes a few of the deeper/less noticable bugs regarding to translations, such as having "30-day" insted of "30 days" in a few places (with our translators not getting a clue which is correct)

I tested all of them manually, so this is Fine

Pull request overview

This PR improves internationalization (i18n) by making hardcoded English strings translatable. It fixes inconsistencies where time periods were displayed as "24-hour", "30-day", and "1-year" instead of the more natural "24 hours", "30 days", and "1 year" by implementing proper pluralization. Additionally, it makes various accessibility attributes (aria-labels and alt text) translatable.

Key changes:

• Replaces hardcoded time period keys (-hour, -day, -year) with pluralized translation keys (hour | hours, day | days, year | years)
• Converts static aria-label and alt attributes across 13 Vue components to use dynamic translations
• Updates Confirm.vue component to use translatable defaults for "Yes" and "No" buttons
