Add Store.withUser(ctx, userID, fn) — a single choke point that BEGINs a tx,
sets the transaction-local GUC tapir.current_user_id via
set_config(..., true), runs fn, and commits. set_config is used over SET LOCAL
because it is parameterizable; the local flag means the value auto-resets on
commit/rollback so a pooled connection never leaks one request's user into the
next.
Route all 9 DB-touching methods through it (Deliver, HasSummary, SeenVideoIDs,
ListSummaries, GetSummaryByVideo, SetAction, ClearAction, ActionsFor, and
UpsertVideo; attachActions flows via ActionsFor). Scoping is now structural —
not a per-query opt-in someone can forget — and arms the migration-003 RLS
policies. Method signatures and existing WHERE clauses are unchanged (defence in
depth; superuser DSNs in existing tests bypass RLS so behaviour is preserved).
