Python VFS decoder rejects runtime statistics and console message URIs

### Feature Summary

The Python VFS decoder lowercases the resource suffix before matching it against the canonical resource enum. Texera produces the camel-case suffixes runtimeStatistics and consoleMessages, so both valid URI types are rejected as unknown. The Scala decoder accepts the same canonical suffixes.

Before: runtimeStatistics and consoleMessages raise ValueError, while result and state decode.

After: all four canonical Texera resource suffixes decode, and unknown suffixes remain rejected.

Reproduction evidence:

1. Call VFSURIFactory.decode_uri with vfs:///wid/1/eid/2/runtimeStatistics.
2. Observe Unknown resource type: runtimestatistics.
3. Call it with vfs:///wid/1/eid/2/opid/demo/consoleMessages.
4. Observe Unknown resource type: consolemessages.
5. Use result or state as a control and observe successful decoding.
