getCertificates() and getCertificates(boolean) now always execute in a fresh Keycloak session via KeycloakModelUtils.runJobInTransaction(), obtaining a new JDBC connection from the pool. This replaces the previous approach of em.clear() (which did not reset the connection), manual retry loops, flush mode manipulation, and in-memory cache fallback — none of which reliably handled the cold-start case where the current session's connection is closed. Verified 1000/1000 under concurrent load (10 workers, no delay). Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Context:
JDBC Connection gets closed under load after some time.
What Changed:
Replace retry/cache complexity with executeInNewSession for reads
getCertificates() and getCertificates(boolean) now always execute in a
fresh Keycloak session via KeycloakModelUtils.runJobInTransaction(),
obtaining a new JDBC connection from the pool. This replaces the
previous approach of em.clear() (which did not reset the connection),
manual retry loops, flush mode manipulation, and in-memory cache
fallback — none of which reliably handled the cold-start case where the
current session's connection is closed.
How was it validated
1000/1000, 0 failures on KC26. The executeInNewSession fix is validated on Keycloak 26.2.0.
