* perf(api): filter peer-run activity in the transcript page query
The transcript loaded a raw page, dropped hidden peer-run rows in memory and
rescanned when nothing visible was left, so a long delegated stretch cost two
queries per hidden page. The page query now joins runs and excludes hidden
peer activity in Postgres, so every page is filled with visible rows. The
kept block kinds live in one list shared by paging, the in-memory filter and
live event forwarding.

* test: port the main-conversation journey fix from #126
Journey 5c fails on main since every space got its own main conversation:
the lookup picked the Lab conversation instead of the home one. Same change
as #126 (including its chart-links warm-up), so this PR can go green; it
no-ops once #126 lands.
