fix(timetable): isolate URL SSRF validation into a tested module

Extract timetable base-URL validation (private/loopback/metadata/NAT64
block lists + DNS-rebinding address pinning) out of the widget router into a
dedicated timetable-options-validation module, and separate the IPv4 and
IPv6 block lists so each family is matched against its own rules.

Board and options routers load the validator lazily at the call site. Carved
out of #6691 so this security-relevant change can land independently of the
larger widget/integration refactor. All 27 existing SSRF unit tests pass.

 4. Write responsive JSX using `data`, `status`, `options`, and temporary `inputs`.
 5. Test and preview, inspect Data and the redacted request journal, then save.
 
+While focus is inside a code editor, use `Ctrl+Z`/`Cmd+Z` to undo and `Ctrl+Shift+Z`/`Cmd+Shift+Z` to redo. The toolbar exposes the same actions. This history is local to that editor; builder-wide undo is not yet available.
+
+Changing the definition, instance options, or credentials invalidates the previous preview and its live-action session. Run **Test and preview** again before treating the data or result as current. Automatic load queries are queued with up to four running at once so larger previews stay within the request limit.
