Security-only, feature-preserving fixes for the free-plugin findings from the 2026-07 audit (tracked with the pro findings on weDevsOfficial/wpuf-pro#1622). - URL custom-field output: esc_url/esc_attr/esc_html (stored XSS) (weDevsOfficial/wpuf-pro#1608) - wpuf_clear_schedule_lock: require edit_others_posts + absint (missing authz) (weDevsOfficial/wpuf-pro#1609) - custom-field labels esc_html, embed URL esc_url_raw, transaction query strict in_array + absint (weDevsOfficial/wpuf-pro#1610) - repeat-field submissions: per-element sanitize on storage (weDevsOfficial/wpuf-pro#1620) - JSON import: allowlist post_type/post_status (mass-assignment) (weDevsOfficial/wpuf-pro#1621) - Settings API: replace deprecated create_function with a closure No functional behaviour change for legitimate flows.

Reformat repeat-field sanitizer closures to WPCS style and restore the original single-line // phpcs:ignore on the settings-desc callback, so the security-fix changes introduce zero new PHPCS errors vs develop. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Security hardening — 2026-07 audit (free plugin)
Free-plugin fixes from the 2026-07 WPUF security audit. Findings are tracked alongside the pro set on weDevsOfficial/wpuf-pro#1622.
Security-only, feature-preserving.
