Fix critical import bugs in linkedin.mjs and wellfound.mjs, clean up status/setup

- linkedin.mjs: LINKEDIN_LINKEDIN_MAX_SEARCH_PAGES → LINKEDIN_MAX_SEARCH_PAGES
  (typo would crash searcher at module load — constant doesn't exist)
- wellfound.mjs: WELLFOUND_WELLFOUND_MAX_INFINITE_SCROLL → WELLFOUND_MAX_INFINITE_SCROLL
  (same — doubled prefix crashes at import)
- status.mjs: remove double-counting ATS from both queue and log
- setup.mjs: replace PM2 instructions with OpenClaw crons
