Move all ClickHouse DML for OpenFlare node access logs into
internal/repository/analytics; model layer keeps domain aggregation and
in-memory test store via a thin adapter. Aligns with goose-managed DDL
and openflare database startup dependency.
Delete the old monolithic openflare-server implementation and rename
Wavelet/ to openflare-server/ to complete the migration consolidation.
Update CI workflows, agent Dockerfiles, and deployment docs for the new
layout (frontend/, docker/Dockerfile).
