Subject: Fix stack overflow and heap-allocate large buffers in Cashu/payment
 path

- tollgate_api.c: increase httpd stack_size to 16384 (was default 4096)
- cashu.c: heap-allocate b64, json_buf, post_body, resp_buf instead of stack
- cashu.c: proper free() on all error paths
- Makefile: replace Go-based tokens target with nutshell wallet targets
- Makefile: add wallet-setup, wallet-info, wallet-balance, mint-token, send-token
