Two authenticated code paths interpolated user-controlled input into a
shell command:
- decode_pay_request passed the bolt11 string into _make_local_call,
which ran it via create_subprocess_shell; a crafted /lightning/
decode-pay-req request could execute arbitrary commands. Switch
_make_local_call to create_subprocess_exec with a discrete argv list.
- blitz_cln_unlock interpolated the wallet password into a
cl.hsmtool.sh invocation run through a shell, and logged it in the
clear. shlex.quote the interpolated values and mark the call
sensitive=True.

If the environment variable BAPI_ENV_PATH is set, the config system will
try to read configs from the given path instead of .env in pwd
If no file is found .env in pwd will be used as a fallback
Env variables will always override settings in .env files.
