admin: title-only information becomes visible text

the client address follows its name as visible muted text in the query tables, the config lock indicator prints its reason beside the tag except in table rows where a page-level note explains the lock instead, and the locked delete buttons describe themselves through that one visible note. the chart legend tooltip is deleted because a named client is deliberately not addressed in the chart, and the dead series address field went with it. titles that merely repeat visible copyable text stay.
