Show Discord channel names and events in startup config

- Fetch channel names from Discord at startup for better readability
- Display each channel on its own line: #channel-name (id) = events
- Refactor platform logging into separate helper functions
- Bump dependencies: discord.js to 14.25.1, ethers to 6.16.0
