# List Wise activities (incoming + outgoing) for a period.
#
# Usage:
#   wise-transactions.sh [--since YYYY-MM-DD] [--until YYYY-MM-DD]
#                        [--month YYYY-MM]
#                        [--type TRANSFER|CARD_ORDER|BALANCE_CASHBACK|FEATURE_CHARGE|BALANCE_DEPOSIT|...]
#                        [--status COMPLETED|CANCELLED|IN_PROGRESS|UPCOMING|REQUIRES_ATTENTION]
#                        [--enrich]                # also fetch /v1/transfers/{id} for the wire reference
#                        [--json]                  # raw list, no table
#
# Backed by GET /v1/profiles/{WISE_PROFILE_ID}/activities — does NOT require
# SCA and DOES expose incoming transfers (unlike /balance-statements which is
# region-restricted for EU personal tokens, see SKILL.md).
#
# Pagination is followed automatically via the cursor.
