Pull request overview

This PR adds a unified PDF report download flow, introduces resizable desktop transcript/insights layout, and refactors AI analysis “tag” actions into more explicit WebSocket message types while adding category metadata and timestamps across the stack.

Changes:

• Add backend PDF report generation + /download/report endpoint and frontend download UI/api.
• Add resizable insights panel in the desktop layout and adjust insight ordering behavior.
• Refactor AI analysis actions (star/unstar/dismiss/undo) into explicit WS messages; add category_code, asked_at, and time_tag_changed fields.
