Auto-detect CI/TUI mode for non-interactive environments and improve patch application robustness

- apply-patches.sh: add signature-marker checks for build-system patches
  to handle cases where reverse-check fails but patch is already applied
- test-baremetal.sh: auto-disable TUI when stdout is not a terminal;
  pass CI=1 to make
- test-live-iso-qemu.sh: pass CI=1 via env to prevent repo cook panic
- scripts/run.sh: auto-disable TUI when stdout is not a terminal;
  pass CI=1 to qemu launch
- repo.rs: improve TUI initialization error messages (raw mode + alternate
  screen) and rustfmt cleanups
- config.rs: auto-detect TTY presence for TUI enablement; use is_terminal()
  instead of relying solely on CI env var
