/**
 * Parses textarea input for bulk API key creation.
 *
 * Supported line formats (one per line):
 *   - `name|apiKey`
 *   - `apiKey` (auto-named as `Key N`)
 *   - `# comment` (skipped)
 *   - blank lines (skipped)
 *
 * `apiKey` may contain `|` — only the first `|` is treated as the separator.
