fix: resolve 5 bugs — auth, ownership, crash, notification, and HTML issues

- dashboard.php: fix PDO parameter count crash for users with no groups
  (used max(count,1) for placeholder count but provided 0 group params)
- index.php: add missing auth check on get_tasks_status API endpoint
  (was accessible without a session, exposing all task data)
- index.php: enforce ownership check on delete_comment API
  (any logged-in user could delete any comment; now requires authorship or admin)
- tasks.php: fix task creation notification using undefined $_SESSION['username']
  (replaced with $current_user['username'] so {assignor} template works correctly)
- tasks.php: remove duplicate id attribute on att-lightbox-body element
