feat(sendblue): add Sendblue iMessage/SMS integration with tools and triggers (#4917)

* feat(sendblue): add Sendblue iMessage/SMS integration with tools and triggers

* fix(sendblue): address review — status-aware webhook dedup, shared routing map, uniform output casing, api-key authType

* fix(docs-gen): skip nested array `items` descriptor in tool input tables

* chore(sendblue): use SendblueSendStyle type, trim URL identifiers

* fix(sendblue): keep is_outbound routing map local to the webhook handler

Avoids a webhook-providers -> triggers cross-subgraph import (single source
of truth in the handler, its only runtime consumer).

* fix(sendblue): remove invalid `tags` from block config (belongs on BlockMeta)
