feat(processor): multiple improvements to the pipeline porting (#1749)

* [Port codebase pipeline] General fixes for RL and scripts (#1748)

* Refactor dataset configuration in documentation and codebase

- Updated dataset configuration keys from `dataset_root` to `root` and `num_episodes` to `num_episodes_to_record` for consistency.
- Adjusted replay episode handling by renaming `episode` to `replay_episode`.
- Enhanced documentation
- added specific processor to transform from policy actions to delta actions

* Added Robot action to tensor processor
Added new processor script for dealing with gym specific action processing

* removed RobotAction2Tensor processor; imrpoved choosing observations in actor

* nit in delta action

* added missing reset functions to kinematics

* Adapt teleoperate and replay to pipeline similar to record

* refactor(tests): remove in-place mutation tests for actions and complementary data in batch processor

* test(tests): add tests for action and task processing in batch processor

* add names for android and ios phone (#1799)

* use _tensor_stats in normalize processor (#1800)

* fix(normalize_processor): correct device reference for tensor epsilon handling (#1801)

* add point 5 add missing feature contracts (#1806)
