Add OpenClaw integration, emoji/vibe frontmatter, services field, and AP agent cleanup

OpenClaw support:
- Add section-splitting convert_openclaw() to convert.sh that routes
  ## headers by keyword into SOUL.md (persona) vs AGENTS.md (operations)
  and generates IDENTITY.md with emoji + vibe from frontmatter
- Add integrations/openclaw/ to .gitignore

Frontmatter additions (all 112 agents):
- Add emoji and vibe fields to every agent for OpenClaw IDENTITY.md
  generation and future dashboard/catalog use
- Add services field to carousel-growth-engine (Gemini API, Upload-Post)
- Add emoji/vibe to 7 new paid-media agents from PR #83

Agent quality:
- Rewrite accounts-payable-agent to be vendor-agnostic (remove AgenticBTC
  dependency, use generic payments.* interface)

Documentation:
- CONTRIBUTING.md: Add Persona/Operations section grouping guidance,
  emoji/vibe/services frontmatter fields, external services editorial policy
- README.md: Add OpenClaw to supported tools, update agent count to 112,
  reduce third-party OpenClaw repo mention to one-line attribution
