GitHub Issue: Translation files not loading

[glazperle]

Description

Added German translation files (de.po) to the i18n folder of the OCA/contract modules, but the translations aren't being applied in the Odoo 17 interface. When using the module, all text remains in English despite following standard procedures for loading translations.

Environment

• Odoo version: 17.0
• Deployment: Docker containers using official odoo:17.0 image
• Module: OCA/contract (branch 17.0), specifically subscription_oca module

Steps taken

1. Added properly formatted de.po file to /mnt/extra-addons/subscription_oca/i18n/
2. Verified German language is installed in Odoo
3. Updated the translation files via Odoo interface (Settings → Translations → Load translations)
4. Set user language preference to German
5. Cleared browser cache and restarted Odoo container
6. Reinstalled module

Troubleshooting attempted

• Verified the module properly loads (is installed and functioning)
• Confirmed the de.po file is accessible within the container
• Tried manually triggering translation updates through UI
• Checked for errors in Odoo logs (none related to translations)

Any help identifying why the translations aren't being applied would be appreciated.
