Link agents to their LINE accounts for better organized management

We've added a "LINE account" field to agent profiles, so each agent can select their own LINE account in their personal account settings.

The setting for who receives post test messages has moved to Settings → Post Article, and recipients are now chosen by "Select agent" instead of "Select LINE account".

When your organization has many agents, this makes it easy to identify and manage testers without having to remember or ask for each agent's private LINE account details, balancing personal privacy with easier management.
