Add team activity stats: thread breakdown, responsiveness, community reach

The team activity dashboard only showed raw message/patch counts and
required manually summing started+other threads to get an active-thread
total, with no signal on how fast the team responds or whether it's
engaging external contributors. Adds deduped active-thread and unique-
contributor counts, a new/joined/continuing thread breakdown, first-
response and backlog metrics, and community-reach counts via a new
TeamActivityStats service, plus a persisted per-team week-start-day
setting instead of a transient request param.
