Pull request overview

This PR applies linting and formatting cleanup across the AWX codebase without intended behavior changes. It primarily normalizes Python/YAML whitespace, removes unused imports or assignments, and applies black-style formatting to selected expressions and literals.

Changes:

• Normalized blank lines, trailing whitespace, comments, and YAML EOF formatting.
• Removed redundant tuple-unpacking parentheses and unused imports/variables.
• Reformatted long literals/calls and preserved selected regex formatting with # fmt directives.

Just a few comments out of curiosity mainly. Good dusting off of the code otherwise.

Is this some sort of bug or perf issue. The last one too. Just curious.

Maybe just debug logic.

This all was old logic that we removed when we first created Ascender (this PR just changes the spacing for the commenting out). This file itself preloads "Demo" inventories, Users, etc.. which we did not want. Instead we add things through our setup playbook if the user desires.
