Jinwoo Hong 52110982ca fix(push): run twelve delivery drains instead of four (#24038)
Four drains, each holding one provider round trip of ~100 ms plus its
database statements, capped delivery near 30/s. Production inflow reached
35/s on 2026-09-30, so the backlog aged past the five-minute TTL and
notifications expired. Twelve drains lift the ceiling to roughly 90/s; the
pool is now six per instance, so the extra drains queue on connections
instead of starving the request path.
