Patterns could only be added on the Syslog page, so an agent asked to map them on the NASes couldn't. list_syslog_patterns gives each pattern's metric and the ready-made ones not added; add_syslog_preset (admin, audited) adds one. The key-picking helper moves beside the patterns for both callers. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
