[FEATURE] Add 24-hour time format support in /usage dialog

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

The /usage command displays time in 12-hour AM/PM format regardless of system locale settings (e.g. LC_TIME=ru_RU.UTF-8 which expects 24-hour format).

Current behavior: Time is always displayed in 12-hour AM/PM format.

Environment:

• OS: Linux
• LANG: en_US.UTF-8
• LC_TIME: ru_RU.UTF-8

Proposed Solution

Expected behavior: Time should respect the system locale or provide a configuration option to choose 24-hour format.
