feat: add https support for condor & hummingbot-api

[david-hummingbot]

PR Description

This PR adds end-to-end HTTPS support between Condor and Hummingbot API, including optional custom CA trust and mTLS client certificates.

What’s included

• Unified server URL handling in Condor (no duplicated URL builder logic)
  • Supports protocol: auto|http|https
  • auto defaults to HTTPS on port 443, HTTP otherwise
  • Validates conflicting host/protocol/port combinations
• TLS policy per server in Condor config
  • tls_verify
  • ca_bundle_path
  • client_cert_path
  • client_key_path
• TLS-aware client initialization
  • Applied to Condor core API client usage
  • Applied to MCP Hummingbot client usage
• MCP server enhancements
  • configure_server supports protocol + TLS/mTLS fields
  • CLI args added for TLS options propagation
• Tests added
  • URL resolution/validation tests
  • TLS factory validation tests
• Docs updated
  • Condor README: HTTPS config patterns, migration notes, troubleshooting, CA/mTLS examples
  • Hummingbot API README: HTTPS setup, cert generation guidance, Condor integration

Setup automation (Hummingbot API)

• Added interactive cert generation in setup.sh
• Added Make targets:
  • make generate-certs
  • make run-https
  • make show-certs

Backward compatibility

Existing Condor configs continue to work unchanged. If protocol is omitted, Condor defaults to auto behavior.
