ssmithxandClaude Sonnet 5 b6ffb5a31d fix(cuprate): enable fast_sync and raise DB cache — 45% CPU on amishparadise ...

The default manifest baked in the exact broken config found on
amishparadise: no fast_sync (defaults false, forcing full ring-sig/RandomX
verification on every block) and target_max_memory capped at ~2.8GiB,
which starved cuprated's DB cache into constant eviction/flush (595GB/24h
of block I/O on a node just appending ~2MB blocks every 2 minutes). A
reference node with fast_sync = true and an 8GiB cache ran at 2.8% CPU
at the same chain height and block rate.

Set fast_sync = true and target_max_memory = 8GiB to match the healthy
reference config, and raise resources.memory_limit from 4Gi to 10Gi so
the container still has headroom above the larger cache.
