sessions: default new sessions to no agent (raw chat)

Was picking the alphabetically-first agent from AGENTS.md ("Code
Reviewer") which felt presumptuous. New sessions now create with
agent_id=null; user picks from the AgentPicker if they want one.
Removes resolveDefaultAgent helper + the getAgentsForProject import
since this was the only caller. The project SELECT no longer needs
the path column either.
