chore(api): regenerate openapi.json (transition-latency fields + held drift)

Adds StreamInfo.time_to_first_frame_ms / last_resize_ms (latency plan P0.1)
and folds in the drift the spec already owed from the held working-tree
consolidation (version 0.12.0, pnp_disable_monitors description, the
conflicting-host 'conflicts' summary field) — the drift test was already
red before this branch; it is green at this commit.
