Power-series: bind history to account id, not name

The live lookup only populates player_id when ranks are attached
(_sm_attach_level_ranks), which normal lookups skip — so recorded
points were key'd by name (or dropped), and the chart (which queries
by id) found nothing. Now the recorder resolves the account id from
the scanner-maintained leaderboard by name when the result lacks a
player_id, and stores strictly under id:<player_id> (no name fallback),
so history survives renames and never fragments by name. Harden the
name->id leaderboard scan against concurrent-mutation RuntimeErrors.

Verified end-to-end: a normal lookup (player_id=None) and a scanner
ingest push both now record an exact point under the account id;
sub-1-Qnt accounts are still skipped.
