* feat: persist client last online and expose API
* feat(ui): show client last online in table and info modal
* i18n: add “Last Online” across locales
* chore: format timestamps as HH:mm:ss
- Hide the “Created” and “Updated” columns in the clients
- Ensures the “All-time Traffic” column no longer overlaps with adjacent columns.
- Improves layout readability and prevents UI cluttering after the v2.6.7 update.
