Metrics translation support

[cka-y]

In order to support future translation efforts, we need to add all labels, column titles, and table titles in the UI for the metrics feature to the internationalization files. This will ensure that all user-facing text is easily translatable.

Tasks:

1. Identify all UI elements in the metrics feature that require translation (labels, column headers, table titles, etc.).
2. Add these strings to the appropriate i18n files for each supported language.
3. Replace hardcoded text in the metrics feature with references to the i18n files.
4. Verify that the metrics UI correctly pulls text from the i18n files.

Outcome:
The metrics UI should be fully prepared for future translations by referencing all translatable text from the i18n files.
