Adds a section explaining that self-managed Kibana re-reads kibana.yml and re-applies its logging configuration on SIGHUP, without a restart. Useful for temporarily raising verbosity while troubleshooting. Relates to elastic/kibana#271682. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
Documents that self-managed {{kib}} re-reads
kibana.ymland re-applies its logging configuration when it receives aSIGHUPsignal, without a restart. This is the reliable no-restart path for temporarily raising verbosity while troubleshooting (adjust a logger level or meta filters, reload, capture logs, revert, reload again).Adds a "Reload the logging configuration without restarting" section to the self-managed Configure Kibana page, covering:
kill -HUP <pid>workflow and the Dockerdocker kill --signal=HUPvariant.Reloaded logging configuration due to SIGHUPlog line).SIGHUPunavailable → restart instead).Scoped to logging on purpose:
SIGHUPre-reads the wholekibana.yml, but logging is the configuration that Kibana deliberately re-applies live.Relates to elastic/kibana#271682 (parent epic elastic/kibana#257240).
