Add an optional `max_blocks` to the Api config that trims the tail to keep at most `max_blocks` from the head.

Goal
If the archival data got stuck, the storage grows until running out of disk space leading to unpleasant consequences.
We can't reliably prevent it from happening. But we can sacrifice older blocks to keep serving the real-time data. Much less users will be affected by a gap than by a stale head.
