Ensure non-admin users cannot enable columns reserved for administrators
across the following hooks:

* web/src/hooks/usage-logs/useUsageLogsData.js
  - Force-hide CHANNEL, USERNAME and RETRY columns for non-admins.

* web/src/hooks/mj-logs/useMjLogsData.js
  - Force-hide CHANNEL and SUBMIT_RESULT columns for non-admins.

* web/src/hooks/task-logs/useTaskLogsData.js
  - Force-hide CHANNEL column for non-admins.

The checks run when loading column preferences from localStorage, overriding
any tampered settings to keep sensitive information hidden from
unauthorized users.
