feat: initial implementation of Cast GHL Provider
Complete MVP implementation of the Cast GHL Conversation Provider bridge:
- Go module setup with chi router and mongo-driver dependencies
- Config loading with env var validation and defaults
- MongoDB token store with upsert, get, update, delete operations
- Cast.ph SMS client with 429 retry logic and typed errors
- Phone number normalization (E.164 ↔ Philippine local format)
- GHL OAuth 2.0 install/callback/refresh flow
- GHL webhook handler with ECDSA signature verification (async dispatch)
- GHL API client for message status updates and inbound message stubs
- Multi-stage Dockerfile, docker-compose with MongoDB, Woodpecker CI pipeline
- Unit tests for phone normalization, Cast client, GHL webhook, and OAuth handlers
