Outstanding flake8 findings (manual fix required)

flake8 produced 1172 findings across the codebase (mostly E501 line-too-long, plus some F401 unused imports and F841 unused variables). These require manual attention and are not addressed by this PR. A representative 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
analyzer/admin/__init__.py:7:89: E501 line too long (94 > 88 characters)
analyzer/admin/ml_admin.py:250:89: E501 line too long (141 > 88 characters)
analyzer/analyzers/case_statement_analyzer.py:77:89: E501 line too long (154 > 88 characters)
... (1172 total findings — full output in CI logs)

Do NOT merge this PR without review — it is auto-generated by the weekly lint routine.
