The PUT endpoint was re-merging old DB messages (which already included
previous merges) with disk messages on every turn, causing duplication.
Now the client passes resumedMessageCount so the server always slices
only the original pre-resume messages before concatenating.

- Add saved_sessions table and CRUD endpoints (save, list, resume, update, delete)
- Save is instant (no LLM summarization), stores exact conversation with tool calls
- Resume loads full message history into chat UI, sends transcript to agent on first message
- Auto-save updates DB after every agent response once a session is saved
- Delete old filesystem-based session/group management (sessions router, useChatSessions, useChatGroups)
- Clean up ChatHeader, SessionList, ChatDetailPanel for saved sessions flow
