docs: rewrite user docs, fix modal scroll, webhook URL, and sccache

Rewrite all public documentation to be user-facing only:
- Remove deployment, configuration, and self-hosting sections
- Add guide pages for SBOM, issues, webhooks & PR reviews
- Add reference pages for glossary and tools/scanners
- Add 12 screenshots from live dashboard
- Explain MCP, LLM triage, false positives, human-in-the-loop

Fix edit repository modal not scrollable (max-height + overflow-y).
Show full webhook URL using window.location.origin instead of path.
Unset RUSTC_WRAPPER in agent cargo commands to avoid sccache errors.
