tlc: fix CTRL+O crash + terminal resize + wire LOW dialog modules

- recipe.toml: stage tlc-pty-login binary alongside tlc/tlcedit/tlcview
  (was missing from ISO, causing CTRL+O subshell spawn failure on Redox)
- app.rs: run_external() catches spawn errors instead of propagating via ?
  (prevents app exit when subshell/command fails to spawn)
- app.rs: add terminal resize detection to event loop
  (tracks last_size, calls terminal.clear() + render() on size change)
- mod.rs: add missing module declarations for chattr_dialog, connection_dialog,
  encoding_dialog, filter_dialog (enables 36 new dialog tests, 1022 total)
