Radix UI Tabs and Accordion unmount inactive/closed content from the DOM
by default. This caused hidden form inputs to be missing from FormData on
submit — saving while on the Block tab wiped all Allow rules (and vice
versa), and saving with the advanced accordion collapsed wiped redirect
URL, trusted proxies, and response settings.
Fix by adding forceMount to TabsContent and AccordionContent so all form
fields remain in the DOM regardless of which tab/panel is visible.
Also adds E2E regression tests covering both scenarios plus the RFC1918
preset, with proper afterEach cleanup to prevent test interference with
concurrent workers.
