Admin members: resolve sponsors against every account, not the page's 500

The Members page loads the newest 500 accounts and built its sponsor name
lookup from that same list. Once the site passed 500 accounts every sponsor who
joined before that window became unfindable, so the page labelled them "dead
link: <name>" with a tooltip saying the member would fall into the holding
tank. It was doing that to 144 of the 500 rows, including cryptoassets 76
times, and not one token on the whole site is genuinely unresolvable.

Sponsorship itself was never affected: assignment at purchase time looks each
token up directly rather than scanning a list.

accounts.identities() returns the identity columns for every account with no
limit, which stays cheap at any size, and the page uses that for the lookup
while still showing 500 rows.
