Every documented command / flag / example now matches `dws <svc> --help`:
- drop phantom commands (attendance class/group/vacation/..., contact label,
ding message list/receiver-status) that map to undeployed tools.
- fix runtime-failure flags (mail --body→--content, doc/calendar/minutes
pagination, chat send-by-bot @-flags, wiki member --users).
- route role/duty "who is responsible" queries to `aisearch person --dimension
duty` instead of the removed `contact label`.
- realign the multi/dingtalk-report skill to entry submit / inbox list / outbox
list.
