Tone down logging for unknown folder types

[labkey-jeckels]

Rationale

We can spam the log file with many redundant complaints about an unknown folder type. Real-world wxamples:

https://app.datadoghq.com/logs?query=%22no%20such%20folder%20type%22&agg_m=count&agg_m_source=base&agg_t=count&clustering_pattern_field_path=message&cols=host%2Cservice&messageDisplay=inline&refresh_mode=sliding&storage=hot&stream_sort=desc&viz=stream&from_ts=1761169394772&to_ts=1762465394772&live=true

Changes

• After the first time hitting an unknown folder type, switch to DEBUG logging
• Track by RowId instead of Container

Tasks 📍

• Manual Testing @labkey-tchad
  • Create two folders with a folder type supplied by a non-critical module, like MS2 or Flow.
  • Remove that module from your deployment directory
  • Start up the server and visit those containers. You should see a single WARN message about the folder type
• Needs Automation - N/A
