fix: env -u PKG_EXECPATH in sudo wrapper + pre-install components at build

PKG_EXECPATH inherited from parent caused pkg bootstrap to treat argv[1] as
a module path. Fix: env -u unsets only PKG_EXECPATH so bootstrap starts fresh
while all auth/session vars are preserved. Depth guard prevents loops.

Also pre-run component installation during Docker build so the sudo code path
is never hit at runtime.

# ── Fake sudo wrapper ────────────────────────────────────────────────────────
# The purevpn-cli pkg bootstrap uses argv[1] as the main module path when
# --install-missing-components is present (causing "Cannot find module '/--connect'").
# Fix: move --install-missing-components to argv[1] so the bootstrap handles
# it as its own flag rather than trying to load '--connect' as a script.
# Clean env (env -i) prevents parent env vars from interfering with pkg startup.
# Unsets PKG_EXECPATH so the child's pkg bootstrap starts fresh instead of
# treating argv[1] as a Node.js module path. Depth guard stops recursion.
