fix(env): mkdir the envFile's parent dir and throw on upload failure

For nested envFile paths (e.g. apps/backend/.env.production in a
monorepo workspace) \`mkdir -p \${appPath}/shared\` isn't enough — the
\`echo|base64 -d > \${sharedEnv}\` redirect silently fails because the
parent directory doesn't exist. The CLI still printed "Uploaded to
..." because executor.exec doesn't check exit codes, and the symlink
was created pointing at a non-existent file, causing the next deploy
to break with an obscure ./.env sourcing error.

Switch to execOrThrow on each step and mkdir the actual parent of
sharedEnv via dirname.
