[Feature] Improve Trash Page Text for Better Readability of Retention Period

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

The feature

Currently, the trash page in Immich displays the message:
"_Trashed items will be permanently deleted after X days._"

However, for users who set long retention periods (e.g., 1,825 days for 5 years), this message becomes less intuitive. It would be helpful if the system could automatically format the retention period into a more human-readable format, such as:
• "Trashed items will be permanently deleted after 5 years."
• "Trashed items will be permanently deleted after 6 months."
