fix: keep slack message controls

CHANGELOG.md

@@ -76,6 +76,7 @@ Docs: https://docs.openclaw.ai
 - Slack/exec approvals: cap native approval metadata context to Slack's element and text limits, so large approval details no longer make Slack reject the approval card. Thanks @slackapi.
 - Slack/commands: cap native command argument-menu fallback rows to Slack's message block limit, so large plugin choice lists no longer make Slack reject the generated menu. Thanks @slackapi.
 - Slack/commands: drop fallback command argument buttons whose encoded values exceed Slack's button-value limit, so one oversized plugin choice no longer makes Slack reject the whole menu. Thanks @slackapi.
+- Slack/messages: merge message-tool presentation and interactive blocks on Slack sends, so buttons and selects are no longer dropped when a structured message body is also present. Thanks @slackapi.
 - Channels/WhatsApp: require Baileys outbound message ids before marking auto-replies delivered, so transcript text and ack reactions no longer make failed group replies look sent. Fixes #49225. Thanks @TinyTb.
 - CLI/update: scope packaged Node compile caches by OpenClaw version and install metadata, so global installs no longer reuse stale compiled chunks after package updates. Thanks @pashpashpash.
 - Channels/Voice call: keep pre-auth webhook in-flight limiting active when socket remote address metadata is missing, so slow-body requests from stripped-IP proxy paths still share the fallback bucket. (#74453) Thanks @davidangularme.
