fix(admin): render the ticket process form as a dedicated view

action=process used to append the process form into the tickets table as
a bare <form><table> inside <tbody> — invalid HTML that browsers reflow,
leaving the ticket list stacked below the submit button. Render the
process form as its own view (early return, list and pagenavi skipped,
with a lookup fallback beyond the current page slice) and keep the list
view free of form injection.
