support bot, bots: paginate chat scan (#6935)

* bots: document APIGetChats command and CRApiChats response

* bots: regenerate API docs and TypeScript types

* simplex-chat-nodejs: add apiGetChats

* support bot: avoid OOM on large databases

apiListGroups / apiListContacts return every record in one response and
overflow V8's string allocation on large DBs. Replace list-then-find-by-id
patterns with apiGetChat(type, id, 0) lookups, and the one genuine scan
(refreshAllCards) with paginated apiGetChats, count=1000.

* support bot: update test assertions to match current message text

* bots: simplify PaginationByTime, expose only PTLast

* simplex-chat-nodejs: bump types and nodejs versions
