ci: reduce e2e-api-v2 test overhead with caching and Jest optimizations (#26331)

* perf: increase E2E test shards from 4 to 6 for faster CI

Increase the number of parallel E2E test shards from 4 to 6 to reduce
overall CI wall-clock time. Each shard runs on a separate 4-vCPU runner
with 4 workers, so adding more shards increases total parallelism.

This should reduce E2E test time from ~3 minutes per shard to ~2 minutes
per shard by distributing tests across more parallel jobs.
