beads-server: add presence_claims table for agent coordination

Browse source 
Adds the schema for the new agent presence board. Live Dolt is updated
via a hashed-named one-shot Job; the ConfigMap entry preserves fresh-PVC
init.

Also pins the Dolt image to 2.0.3 — :latest on dolthub/dolt-sql-server
currently resolves to 0.50.10, whose docker-entrypoint.sh references an
undefined docker_process_sql function and crash-loops on every init
script in /docker-entrypoint-initdb.d. Keel can still bump this tag
in-cluster (image is in lifecycle.ignore_changes).
