fix(slack): convert Unicode emojis to Slack shortcodes for reactions

- Add node-emoji dependency for Unicode → shortcode conversion
- Update normalizeEmoji() to handle both Unicode (👀) and shortcode (👀) formats
- Fixes issue where Unicode emojis in config (messages.ackReaction) would fail with 'invalid_name' error
- Backwards compatible: existing shortcode configs continue to work

Resolves the root cause by making Slack emoji format transparent to users.
