feat: Phase 2 - Pterodisbot Integration Features

- Implemented SlashCommandHandler with Pterodisbot-specific commands:
  - /server_status: Shows server list with dropdown selection
  - /refresh_embeds: Admin command to refresh all embeds
  - /purge_embeds: Admin command to purge all embeds
- Implemented InteractionHandler for Discord interactions:
  - Button clicks (Start, Stop, Restart, Show Address)
  - Select menus (Server dropdown)
  - Slash commands (via InteractionHandler)
- Added EmbedRenderer widget for rich Discord embed rendering
- Added ComponentRenderer widget for buttons, selects, action rows
- Added MessageEntry and MessageList widgets for channel message display
- Added ChannelMessageView for full channel view with header, messages, input
- Implemented TUI navigation between guilds, channels, messages
- Added ChannelMessageView widget with message rendering, embeds, components
- All 19 tests passing
