feat(accounts): surface prolite as its own plan filter and label

Add a ProLite chip to the plan filter row and render the raw prolite
value as "ProLite" in the plan column so operators can spot and slice
the $100 Pro tier distinctly from full Pro.

Filter comparison switches to the raw plan_type so Pro and ProLite
become independent buckets; behavioral paths (usage bars, score bias)
still normalize prolite into pro, unchanged.
