 * tasks.php — manage task system: channel-join tasks + free-form text tasks.
 *
 * Permission: owner OR 'tasks'.
 *
 * Three sections:
 *   1. Pending text-task answers (mini-review queue, links to task_detail).
 *   2. All tasks table (edit / delete actions).
 *   3. Create-task form (channel | text) with 3-currency rewards.
 *
 * Reward model: three independent amounts (reward_game_tokens, reward_toman,
 * reward_ntx) — 0 means "don't give that currency". Any combination is allowed.
 * The legacy reward_type/reward_amount params are passed as 'game_token'/0 for
 * backward compatibility; the three new params are the source of truth.
 *
 * POST actions (CSRF-guarded by index.php before this file loads):
 *   - create_task
 *   - update_task
 *   - delete_task
