fix: return SyncLog error entry instead of False when local path is not allowed

[geoClink]

Bug

When syncing a local storage folder with a path that is not in LOCAL_STORAGE_PATHS, the import_all method in local.py returns
False. The query_synced_folder endpoint then passes this boolean to SyncLogSerializer, which crashes with AttributeError: 'bool' object has no attribute 'status', resulting in a 500 error.

Root Cause

Local.import_all() returns False on a path validation failure instead of a SyncLog object. The serializer expects a SyncLog

Fix

Instead of returning False, create and save a SyncLog entry with status='ERROR' and return it. This is consistent with the success
path already in the same method and gives the serializer a valid object to work with.

Testing

Unable to test locally, but the fix follows the exact same pattern as the success case already in local.py.

This is ready for review. Instead of returning False on a disallowed path, the method now creates and returns a SyncLog error entry, consistent with the success path in the same method.
