feat: overhaul session documentation, PSA notes, and client communications

- Reformat PSA resolution/escalation notes: clean single-line header,
  steps with engineer responses inline, remove duplicate timing blocks,
  remove AI confidence section, add follow-up recommendations
- Standardize time display to decimal hours (e.g. 0.25 hrs) across all
  note formatters and status update context
- Add follow_up_recommendations to SessionDocumentation schema and
  surface in SessionDocView; extracted from resolution suggestion steps
- Add _build_what_we_know() helper: uses session.evidence_items when
  cockpit branch merges, falls back to deriving findings from steps
- Fix option label lookup in generate_status_update (was passing raw
  machine values to AI instead of human-readable labels)
- Add 'What We Know' section to status update ticket notes prompt
- Improve _build_session_context in resolution_output_generator to
  include intake text and full step details instead of truncated chat
- Add request_info audience type: client-facing information request
  that skips the length step and generates a numbered question list
- Improve client_update and email_draft prompts with per-context
  guidance (status/resolution/escalation) and fix escalation subject
  line from 'Specialist Review' to 'Specialist Assistance'
