pi session context persistence, fix new session button, add clear all sessions

Browse Source 
- handle pi process death by nulling piProcess ref so next message respawns
- replay conversation history on respawn via --session flag
- fix user message JSONL format to array for pi compatibility
- fix container sessions mount to match storage path
- fix ChatPanelWrapper: key on inner component so usePiChat resets on new session
- add bulk delete sessions endpoint and clear all button in chat header
