feat(seasonpass): bump mainnet image to git-cc9e3f8 (deploy SeasonPass#306 /ping resilience)

Deploys NineChronicles.SeasonPass#306 to mainnet: /ping -> async + DB
pool_timeout 60s->10s, so a transient DB-pool exhaustion no longer starves
the sync liveness probe and causes spurious pod restarts (exit 137).

seasonpass-api has been in a liveness restart loop (17 restarts / 3 days).
Service-side, not network: during the deaths the shared postgres served the
independent tx-tracker fine and TCP latency was 0-2ms; the API exhausts its
own 30-conn pool in brief concurrency bursts (threadpool 40 > pool 30) and
the sync /ping cannot be scheduled.

Code diff vs deployed git-c5c0ed5f is only the 2 api files; c5c0ed5f is the
same skip-empty-claim change as main HEAD 715a916, so workers/trackers get
equivalent code + a clean restart. Images verified present for all 3 repos.
