Summary

• In Block Kit mode the Slack block hid its message text field and always sent ' ' as text, so every Block Kit message pushed a blank notification preview
• Send, ephemeral, scheduled and update now keep their text field visible in Block Kit mode as optional notification and fallback text; it is still required only in plain-text mode
• The params mapping already forwarded text/updateText when set, so a filled field now reaches Slack

Type of Change

• Bug fix
