Add confessions to setup wizard, fix more mojibake and dead config

Setup wizard:
- Add 'confessions' module to the MODULES map so admins can configure
  the /confess channel via /setup (was only editable in config.yml).

Mojibake (double-encoded UTF-8) in SlashCommandManager:
- /seen embed author: '·' -> '·' (U+00B7)
- /confess footer: '·' -> '·' (U+00B7)

Startup banner:
- 'Modules: x/15' was wrong - only 13 modules exist. Introduce
  TOTAL_MODULES constant (13) with a comment tying it to
  countActiveModules and the module fields.

Dead/misleading config (bump config-version 4 -> 5):
- Remove leaderboard.tracked-stats and leaderboard.top-count - neither
  is read anywhere (stats are hardcoded; only per-page is used).
- Wire up api.enabled - it existed in config but the API service was
  registered unconditionally. Now honoured in onEnable.
- Fix reaction-roles comment that referenced a non-existent
  /zdiscord reactionrole subcommand.
