Outstanding flake8 findings (manual fix required)

There are 1172 flake8 findings remaining that require manual fixes (not auto-fixable by black/isort). The majority are E501 line-too-long violations. A sample:

analyzer/admin/__init__.py:16:1: F401 '.ml_admin' imported but unused
analyzer/admin/__init__.py:16:1: F401 '.query_admin' imported but unused
analyzer/admin/__init__.py:16:1: F401 '.user_admin' imported but unused
analyzer/analyzers/base.py:19:1: F401 'django.core.cache.caches' imported but unused
analyzer/analyzers/base.py:158:9: F841 local variable 'start_time' is assigned to but never used

Full flake8 output was captured during this run (1172 lines). Notable error codes:

• E501 — line too long (majority of findings)
• F401 — imported but unused
• F841 — local variable assigned but never used
• E402 — module level import not at top of file

Additional Notes

This PR was created automatically by the QueryGrade weekly lint routine (scheduled task). Do not merge without human review.
