fix error

[gogonzo]

closes insightsengineering/teal.reporter#302
TealReporterCard inherits from ReporterCard, when loading from file TealReporterCard$dispatch_block(block_class) is triggered. Because TealReporterCard is in teal namespace, TextBlock is failing as TextBlock is a teal.reporter (private) object.

I hope code fix is self explanatory.

I can confirm I see an error on the bottom right corner when uploading the report (even if generated with this branch) on main branch:

Loading reporter error!
Please contact app developer

When I upload the report on this branch I do not longer see this error.

I wonder if there's a way to test this. This function seems important and that it had slipped through checks.
