feat(terminal,cli): docker_extra_args + display.timestamps

Two independent opt-in QoL toggles, both off by default.

terminal.docker_extra_args:
- List of extra flags appended verbatim to docker run after security
  defaults. Useful for adding capabilities (e.g. --cap-add SETUID) or
  other docker run options not exposed by existing config keys.
- Non-string entries are logged and skipped.
- Also available via TERMINAL_DOCKER_EXTRA_ARGS='[...]' env var.

display.timestamps:
- Appends [HH:MM] to user input bullet and the assistant response box
  header. Single hub in _format_submitted_user_message_preview()
  covers both single-line and multi-line user previews; assistant
  response label gets the timestamp at box-open time.

Closes #1569 (timestamps).
