Wallet receive via health task queue (no separate TLS worker)

- Removed standalone TLS worker task (couldn't allocate 16KB internal stack)
- Added wallet receive queue to mint_health task (already has 16KB stack + working TLS)
- health_task processes wallet tokens between probe intervals (1s poll)
- tls_worker_set_queue() registers queue from mint_health_start()
- Fallback to synchronous receive if queue not available
- Added freertos/queue.h and tollgate_api.h stubs for unit tests
- Added BaseType_t/UBaseType_t/TickType_t/pdFALSE to FreeRTOS stub
- Full payment round-trip confirmed: 2 payments → 41 sat balance
