tunnel-rat is how pagination and full-page form buttons get into the sticky footer of ContentPane. It hasn't had a release since 2023 and it installs its own copy of zustand 4 next to our zustand 5. It was written to move elements between React renderers, which we don't need: we only have one renderer, so createPortal is sufficient. This PR replaces the tunnel with a PageFooter component that portals its children into the footer element, which ContentPane registers in a small zustand store through a ref callback.

Why it's better:

• Footer content is rendered once, in place. tunnel-rat copied each source's children into a store in a layout effect on every render of the page and rendered them again from the store.
• One fewer dependency, no second zustand, and less code.

Potential issues and why they don't matter:

• tunnel-rat kept multiple sources in a defined order. Portals append in mount order. But we don't care because only one thing is ever in the footer at a time: FullPageForm is the only user of page actions, and no full-page form has a paginated table.
• React events from footer content now bubble through the page's tree before reaching ContentPane. No page has a handler on an element around its table or form buttons, so nothing changes.

Added an e2e test that navigates from the projects list into a project, to the instance create form, and back, checking that the footer shows pagination, then the form buttons, then pagination again.
