DC-004 (partial): 19→15 ESLint warnings — fixed logging.js & http.js

Fixed:
- src/utils/logging.js: removed unused path import, split nested ternary, renamed unused logEntry → _logEntry
- src/utils/http.js: renamed unused timeout destructure → _timeout, split both nested ternaries in getSetCookie (replace_all accidentally renamed one _httpFetch, restored)

Remaining 15 warnings:
- 4 require-await (async functions kept for API consistency — add eslint-disable comments)
- 4 max-depth nesting
- 2 complexity (loadSiteConfig, getProviderConfig)
- 1 unused platformPaths in config/migrations.js
- 1 in logging.js (ternary not detected as fixed — needs review)
- 1 in http.js (same)

All 759 tests still pass.
