fix(whatsapp): remove 120s timeout on bridge npm install (#13339)

The WhatsApp bridge depends on @whiskeysockets/baileys pulled directly
from a GitHub commit tarball, which on slower connections or when
GitHub is sluggish routinely exceeds 120s. The hardcoded timeout
surfaced as a raw TimeoutExpired traceback during 'hermes whatsapp'
setup.

Switch to the same pattern used by the TUI npm install at line
~945: no timeout, --no-fund/--no-audit/--progress=false to keep
output clean, stderr captured and tailed on failure. Also resolve
npm via shutil.which so missing Node.js gives a clean error instead
of FileNotFoundError, and handle Ctrl+C cleanly.
