Prevent self-hosting app from re-matching/re-creating people on no-op updates (#21406)

The match-telemetry-event-with-people logic function triggers on
selfHostingUser.* (both created and updated) and unconditionally wrote
personId back to the record on every run. Since the handler's own write
produces an updated event — and the telemetry webhook also updates
unrelated fields (name, serverUrl, etc.) on returning signups — the
matching logic re-ran unnecessarily, querying people and writing on each
pass.

This adds an early-return guard so the handler only does work when
there's actually something to match:

Skip when the selfHostingUser is already linked (personId set) and the
primary email hasn't changed.
Still (re)match on first link and on genuine email changes — the
legitimate reasons for listening on updated.
The guard reads before.email.primaryEmail via an 'before' in properties
narrowing so it stays type-safe across the create/update event union.
