improvement(slack-trigger): expose view, message, and state on interactivity payloads (#5279)

The native Slack trigger flattened every interaction into scalar event.* fields
and dropped the structured objects, so view_submission and block-rewrite
workflows could not read view.state.values, view.private_metadata, or
message.blocks. Pass the full Slack view and message objects through, plus the
top-level block_actions state (state.values), and declare them in the trigger
outputs so they surface in the editor. Additive and backwards compatible:
existing flattened fields are unchanged and new fields default to null.
