Fix modules to use `teal_data` instead of `tdata`

[gogonzo]

part of https://github.com/insightsengineering/teal/issues/937

installation instructions:

staged.dependencies::dependency_table(
  project = "insightsengineering/teal.modules.hermes@https://github.com",
  project_type = "repo@host",
  ref = "refactor",
  verbose = 1
) |>
staged.dependencies::install_deps()

Why only a single branch/PR for this?

The tdata changes are well modularised into experimentSpec.R and adtteSpec.R which process the tdata and provide functions that can be used in the modules to get the MAE data, and the modules are using this MAE data throughout and do not care about tdata or teal_data.
