V1.3.1FixV1.3.1 — antd v6 fixes, CORS auto-retry, Rich Text Editor UX2026-05-07

Sweep of antd v6 deprecation warnings, transparent CORS auto-fallback for SOAP Client and WSDL Parser, WSDL request headers support, Rich Text Editor formatting reliability and notepad UX, and a pkcs12 hydration fix.

SOAP Client — CORS auto-retry
  • Direct browser fetches that fail with a network/CORS error now **automatically retry through the server proxy** — no need to toggle 'Force server proxy' manually.
  • Fixed `Space direction="vertical"` → `orientation="vertical"` antd v6 deprecation in the SSL tab.
WSDL Parser — request headers & merged XSD
  • New collapsible **Request Headers** section on the WSDL input panel — configure headers in form or JSON mode, applied to every WSDL and XSD fetch.
  • WSDL and XSD fetches now **auto-fallback through the server proxy** on CORS failure (same pattern as SOAP Client).
  • **External XSD** section is now collapsed inside the WSDL input area rather than a separate tab — less clutter, optional by default.
Rich Text Editor — formatting & UX
  • All toolbar buttons now use `onMouseDown` with `preventDefault` to keep editor focus and selection intact — formatting commands (Bold, Italic, lists, alignment, colours) now work reliably.
  • Toolbar link button saves the selection on `mousedown` so the selected text is correctly linkified after the modal opens.
  • Editor area restyled as a **document canvas**: white paper background, increased padding, max-width constraint, and a subtle box-shadow separating it from the toolbar.
  • Removed 'Start typing here…' default placeholder — new documents open with an empty editor.
antd v6 deprecation fixes
  • `gzip-tools`: replaced static `message.success` import with `messageService` to avoid 'cannot consume context' warning; `Alert message=` → `title=`.
  • `ssh-key-generator`: `Alert message=` → `title=`.
  • `pkcs12-tool`: added `mounted` guard around `Input.Password` to suppress `data-sharkid` browser-extension hydration mismatch.
  • `SslConfigSection`: `Alert message=` → `title=`; `Space direction=` → `orientation=` (fixed in previous patch, documented here).
