fix(ui): hide Created/Updated columns and fix issues in small displays (#3400)

- 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.

Closes #3399
