feat: show each account's plan in the team's accounts table

Per-seat billing context without per-seat subscriptions. PUT-1788 D1 stands: one
tier per team, one Stripe subscription, quantity = seat count. The tier is still
changed once, in the plan card.

Four states, because "on Team Basic" is not true of every row. The owner is the
payer and keeps their own personal plan, so they show as such rather than
inheriting the team's. A suspended seat reads "not billed" -- it stops costing a
per-account charge, which is the same rule the billing summary and the plan
card's seat count already use. A seat of a team that bought nothing reads free,
which is the reduced org-seat allowance. Everyone else shows the tier.

The rule is a helper in teamsConsole so it is testable, like the rest of that
file.

Falsified: dropping the payer branch fails "says the owner is the payer, not a
seat"; dropping the suspended branch fails "says a suspended seat is not
billed".
