(improvement) Migrate from clickhouse to @clickhouse/client

[Blaumaus]

Ticket

Swetrix/roadmap#217

1. Migrated everything from clickhouse to @clickhouse/client - now everything is much easier to use and maintain, there's also no need to write raw (parametrised) SQL insert queries, because the new library offers lots of methods for that.

2. Dropped Redis for analytics data queuing. Now we rely on asynchronous queries for that. Clickhouse server will create batches on it's own and inject them into the database whenever it's ready. Now the data will be saved to the DB and displayed in dashboard almost instantly.
   

3. Errors like Error: 500: Code: 241. DB::Exception: Memory limit (total) exceeded: would use x.xx GiB (attempt to allocate chunk of xxxxxxx bytes), maximum: x.xx GiB. OvercommitTracker decision: Query was selected to stop by OvercommitTracker. (MEMORY_LIMIT_EXCEEDED) (version x.x.x.xx (official build)) will now be prevented because chunks are managed server-side.
