Improve meeting dashboard and analysis context

[vokac-nri]

Summary

• rebuild the meeting workbench so the transcript uses less space and all four analysis panels remain useful
• turn live summary output into an auto-following topic outline with discussion points and higher-value, optional questions
• snapshot meeting context, add a context-plus-transcript export, and preserve legacy-session behavior
• remove forced reasoning/temperature directives and add a 12-line transcript overlap without reprocessing duplicate findings

Verification

• go test -count=1 ./internal/analysis ./internal/llm ./internal/export ./internal/store .
• npx tsc --noEmit
• npm run build
• responsive browser QA at 1280x820 and 960x640

Pull request overview

This PR updates Parley’s live meeting experience by making the analysis UI more “outline-first,” improving analysis prompt context (including bounded transcript overlap), and preserving session context via a stored snapshot that can be exported alongside the full transcript.

Changes:

• Reworks analysis prompting/state to support a topic outline with discussion points, bounded transcript overlap, and less provider-forcing (no fixed temperature / reasoning directives).
• Snapshots meeting context at session creation (with legacy fallback) and adds a “context + transcript” export mode.
• Refreshes the frontend workbench layout (discussion outline + panels) and adds an export-choice dialog.
