feat: add /help, /history, /uptime commands and enhance /status

- /help: detailed guide with examples for all commands
- /status: overall indicator, emoji markers, updated time, status page link
- /history [count]: recent incidents with impact, dates, links (max 10)
- /uptime: component health with last change time
- Split info commands into bot-info-commands.js for modularity
- Register all 7 commands in bot-setup.js
