Language switching not working - UI remains in English regardless of selected language

### Problem Description

Certain fields on the following pages are not internationalized and consistently display in English:

1. **Session Page** - List header titles are not translated.
2. **Session Edit Drawer** - Relevant fields are not translated.
3. **Scheduled Task Page** - List header titles are not translated.

### Expected Behavior

All user-visible text on the aforementioned pages should support internationalization (i18n) and display in the language corresponding to the user's settings.

### Reproduction Steps

1. Switch the application language to Chinese.
2. Navigate to the Session page, Edit Drawer page, and Scheduled Task page.
3. Observe that specific fields remain displayed in English.
