fix(history): address PR #116 review feedback

- console: drop orphaned `/logging chat` reference from
  cons_privacy_setting() — the subcommand was removed, PREF_CHLOG now
  tracks PREF_HISTORY implicitly
- console: delete cons_logging_setting() and remove its call from
  cons_show_log_prefs() — every line in it referenced /logging chat or
  /logging group, both now invalid after the deprecation below
- command: deprecate /logging command. It now prints a single notice
  pointing to /history; CMD_PREAMBLE trimmed (min_args=0, no
  setting_func, syntax/args/examples dropped); subcommand 'group'
  removed from autocomplete

The SQLite history-load gap for /correction off is split out into a
follow-up — out of scope for this PR.
