fix(ui): make Pagination usable server-rendered, surface output errors

Pagination reported the requested page only through its change output, so on a
server-rendered page the controls did nothing: the parent had to own client
state to react, and the emitted page never became a URL. An optional
hrefTemplate now renders the steps and page numbers as anchors, which work
before hydration and without JavaScript and give each page a crawlable URL.
Buttons remain the default for client-owned lists. End steps are clamped and
marked disabled rather than linking past the first or last page.

Output handler errors are no longer swallowed. Nothing awaits invokeOutput, so
a handler that threw became an unhandled rejection that never reached the
console and presented as a control that silently does nothing. Handler errors
are now reported as WRN-DEV-OUTPUT-HANDLER-ERROR.

Regenerates the component reference and the UI visual contract.
