feat: agent setup prompt for new projects

A "Set up with an AI agent" dialog that mints a write-scoped API key and
renders a copyable prompt handing a coding agent everything needed to wire
a repository into a Primora project: telemetry ingest for any language,
db-connections for tracked databases, MCP/CLI agent access, and
verification steps. Opens at the end of new-project onboarding; also
reachable from the project dashboard and Projects page settings.
