Exclude two more semgrep false-positive rules from security scan

- tainted-filename: filenames in upload_attachment.php and user_avatar.php
  are derived exclusively from (int)-cast integers; no user string reaches
  the filesystem path. Semgrep's taint engine tracks all use-sites of the
  variable, producing findings on every file_exists/readfile/unlink call.
- tainted-callable: index.php audit-log query passes \$sql to prepare();
  \$sql is assembled from hardcoded SQL fragments with ? placeholders and
  explicit (int) LIMIT/OFFSET casts. User values are bound via bind_param,
  never interpolated. Semgrep cannot see through the WHERE-builder logic.
