feat(tools): adopt esp-pylib for idf.py logging and errors

Migrate idf.py and its actions to the shared esp-pylib library:
- add esp-pylib (and esp-pylib[ide]) to the core/ide requirements
- base FatalError on esp_pylib.errors.FatalError, keeping the idf.py ctx cleanup
- replace the local raw-ANSI helpers (red_print/yellow_print/print_warning/
  color_print) with esp_pylib.logger.log (warn/err/note/hint) across the
  idf.py actions
- install esp_pylib exception reporting at the idf.py entry point and silence
  the logger during shell completion
- update affected tests for the new prefixes/line wrapping
- add normalize_output() helper and unify terminal env in conftest to handle
  Rich line-wrapping in CI assertions
