www/dokuwiki: update to 2026-07-14a
- Remove patch-wrong-2388-fix: upstream rewrote X-Accel-Redirect handling in http_xaccel_url() which properly handles relocated savedir (FS#2895)
- Fix LICENSE_FILE_BSD3CLAUSE path: simplepie moved LICENSE.txt to LICENSES/BSD-3-Clause.txt
- Add TEST option (off by default) to control installation of test suites, PHPStan static analysis files, and the testing plugin
- Update pkg-plist for new/removed/reorganized files in this release
- Remove ldap and pdo_mysql from USE_PHP: these are only required by the optional authldap and authpdo plugins, not core functionality
