workout_kinds gains a real user_id column (Task 1); workout_type_paces has
none of its own and is scoped via a join to workout_kinds instead, since
it's always accessed through a specific kind.

Part of per-user profile isolation: profile rows are no longer a global
singleton, so every read/write requires the caller's userID. This also
requires scoping ListActivities, ListWorkoutKinds, UpsertActivity,
CreateWorkoutKind, GetSyncState, UpdateSyncState, and ResetAllSyncedData
to userID, plus updating all related tests in the store package.
Manual assignments are the user's definitive word and Race assignments come
from a hard Garmin fact (eventType.typeKey), not a retunable rule -- neither
is ever touched by reclassify again, and Race can no longer be set by hand
via the review queue. Adds an Activities page so this locked/unlocked status
is visible per workout, since Review Queue only ever showed unresolved items.
