List edge functions the SPA calls (self-host checklist)

[telivity-otaip]

Why

web/index.html invokes Supabase Edge Functions (run-search-mt, fetch-jd, resume-match, …). Self-host README should say which are required vs optional.

Task

1. Grep sb.functions.invoke( in web/index.html.
2. Add a section to web/README.md: Edge functions
   • name
   • when the UI calls it (1 line)
   • required vs optional for a minimal board-only install
3. Be honest: function source is not in this public repo; operators must supply their own implementations or use a hosted backend.

Acceptance

• Complete list matching the SPA
• Minimal viable set called out (e.g. board CRUD may work without search/rewrite)
• No private deploy secrets or internal vault paths
