fix(fusion_helpdesk_central): chatter notice no longer collapsed; adds summary

Previous engagement notice used <blockquote> to style the findings
quote. Odoo's mail.thread renderer auto-tags every <blockquote> with
data-o-mail-quote-node="1" and the chatter UI then HIDES the content
behind a "..." widget — exactly the wrong UX since the findings are
the load-bearing content, not throwaway quoted text. Swapped both
quote blocks for styled <div>s with the same visual treatment (left
border, light background, padding) so they render fully inline with
no toggle.

Also expanded the notice to mirror more of what the owner sees in the
engagement email: now includes BOTH "Our reply" (the findings) and
"Summary sent to the owner" (the AI summary). The employee can see
the full context being used for the decision, not just the engineer's
reply. Skipped the Original Request section because the employee
wrote it themselves — would just clutter the thread.

white-space:pre-wrap preserves multi-line findings/summaries that the
engineer typed with line breaks. The two sections are visually
distinct: findings in light blue (matching the email's "Our Reply"
treatment), summary in light grey (matching "Summary for the
Decision" in the email).

Verified live on ticket #54: new message body has no <blockquote>,
no data-o-mail-quote attribute, and contains both section headers
with their content rendered inline.
