activity-sport-type: schema, contract, write/read paths, federation

Implements the activity-sport-type change (specs/activity-sport-type):

- db: nullable `sport_type` column on journal.activities + SportType /
  SPORT_TYPES (text().$type<> convention).
- api: optional sportType on the activity read + create schemas (mirrored
  SPORT_TYPES; @trails-cool/api stays zod-only).
- write: ActivityInput + createActivity persist it; mapSportType() normalizes
  provider strings (Komoot bulk import passes tour.sport; Garmin unset);
  threaded through the unified importActivity.
- read/display: sportType added to the detail/feed/profile loaders and the v1
  REST endpoints; shared SportBadge (glyph + i18n label) on detail, feed, and
  profile; sport-aware feed verb; create-form <select>.
- i18n: journal.activities.sport.* (labels + verbs) in en + de.
- federation: `sport` PropertyValue on the Note when set.

Tests: mapSportType unit table; federation asserts the sport attachment is
present when set and omitted when unset. typecheck + lint + unit all green.
E2E (create→badge) still to add.
