Improve site-check quality: fix broken site configs, add diagnostic utilities, and make self-check report-only by default with opt-in auto-disable. (#2301)

- Fix VK and TradingView checkType; add Reddit and Microsoft Learn API-style probes where appropriate; adjust or disable entries that are unreliable under anti-bot protection.
- Self-check: stop aggressive auto-disable; default to reporting issues only; add --auto-disable and --diagnose for optional fixes and deeper output.
- Tooling: add utils/site_check.py and utils/check_top_n.py (and related helpers) to inspect and rank site behavior against the top-N list
- Scope: aligns with fixing top-traffic / high-impact sites and making diagnostics repeatable without silently flipping disabled flags
