Phase 6e-6f: Break circular dependencies

6e: Extract tls_worker queue from tollgate_api.c into shared tls_worker.c/h
    - mint_health.c no longer includes tollgate_api.h
    - tollgate_api.c no longer defines tls_worker functions
    - Clean circular dependency broken

6f: Move payout_config_t from lightning_payout.h to config.h
    - config.h no longer includes lightning_payout.h
    - lightning_payout.h includes config.h for types
    - Reverse dependency broken

All 21 unit tests pass. ESP-IDF build passes.
