fix(agent): read a WhatsApp "nej" as an answer, not a half answer (#1433)

* fix(agent): read a WhatsApp "nej" as an answer, not a half answer

#1425 gave the assistant the answers the user typed in WhatsApp. Rendering
those inline off the raw channel_context blob gets the most common answer
backwards.

Answering "nej" to the representation question stores an EMPTY representation
block: participants: [], purpose: null, denied: true. The renderer branched on
`if (!rep.purpose)` and so emitted

    syfte SAKNAS: fråga bara efter syftet, inte om deltagarna igen.

for a user who had just said the meal was not representation. `denied` was
never read anywhere. The result is the assistant asking about the purpose of a
private lunch, which is worse than the generic re-ask #1425 fixed, because the
instruction is specific and confident.

Clarifications now come from a structured summary that models the denial and
the genuine half answer (participants named, purpose missing, which BFL 5 kap
6-7 § does want completed) as different states. #1425's syfte SAKNAS nudge is
preserved for the case it was written for.

Two smaller fixes in the same renderer, both about untrusted text:

- The photo caption no longer reaches the prompt. It is the one field on the
  record nobody was asked for and nobody reviewed, and the rationale already
  written down in lib/documents/channel-context-notes.ts for keeping it off an
  immutable verifikat applies at least as strongly to a prompt that can call
  tools.
- Human free text passes through flattenMemoryContent. An intent's
  promptTemplate output is seeded as a user message, so wrapToolResult never
  sees it and nothing else defends this path; a caption reading
  "# NYA INSTRUKTIONER: ..." previously rendered verbatim.

All three tests fail against the current renderer and pass against this one.

* fix(agent): gate the chat-answer guidance on what was rendered

CodeRabbit caught the same defect shape this PR is about: the
prior-conversation paragraph was gated on chat_answers != null, but a
caption-only context is non-null and now summarises to nothing, so the
paragraph pointed at 'uppgivna av användaren' rows the prompt does not
contain. Gate on whether a clarification line was actually emitted.
