wienen 12a82f570a Reduce mailcat to reporting and reorder tools
The prompts used to arrive at this change since the previous commit

User said the real hans mailbox has been reordered, Roundcube filters are uploaded, the sorter and web rule interface are no longer needed, then asked to keep logs and perform the cleanup while retaining unsubscribe capability.

Any special observations that may be relevant for version management for this version. Be brief.

Kept daily report, Sieve policy, folder/reorder scripts, unsubscribe script/data, and log/state files. Removed live sorter, web UI, deploy helpers, old analysis artifacts, backup mirror, and obsolete tests. Verification passed; verplaats_log.json, plan.md, and roundcube.txt remain unstaged/local.
