chore: eliminate all 60 flake8 violations (60 → 0)

- Remove 46 unused imports across 15 core/ files and 4 handlers/ files
- Fix 2 F821 bugs: add missing `import platform` in advanced_techniques,
  add TYPE_CHECKING import for DockerExecutor in sandbox/fallback
- Fix 2 F541: remove f-prefix from strings without placeholders in http/client
- Fix F841: remove unused `tools` variable in resource_handlers
- Fix E261/E302/E303: whitespace formatting in beacon, credential_dumper,
  resource_handlers
- Add noqa: F401 for 8 intentional conditional imports (impacket, lazagne,
  httpx, requests, aiohttp, docker, urllib3 — optional dependency guards)
- Consolidate duplicate typing imports in ad_enum, sandbox/executor
