Subject: [PATCH] fix(voice-call): add missing region/edge uiHints, schema
 patterns, docs

- Add twilio.region and twilio.edge uiHints to index.ts (was only in
  openclaw.plugin.json)
- Add pattern constraints to JSON schema to match Zod validation
- Allow digits in edge regex (^[a-z0-9-]+$) for future-proofing
- Mention region/edge in SKILL.md Twilio config line
