fix(server): reject plugin timeline kinds the app cannot register (#7677)

timeline.append accepted any string as the row kind, but the app registers
renderer kinds with /^[a-z][a-z0-9-]*$/. A plugin that appended a kind such as
repro.card got a successful append, then its client setup threw in
addTimelineRenderer and the whole plugin client failed to load.

The daemon now rejects an append whose kind breaks that rule and names the rule
in the error. The wire schema stays a plain string. Document the rule in the
plugin docs.

Fixes #7326
