Fix Discord slash command acknowledgements to avoid timeout errors

[erikraft]

Motivation

• Prevent the Discord client from showing "The application did not respond" when a slash command is invoked but not acknowledged or the command module is not loaded.
• Make interaction error handling more defensive so failed replies/edit attempts do not leave the interaction unresolved.

Description

• Added a fallback reply when a chat input command is not present in client.commands to avoid silently returning (file: Discord/Bot/src/index.js).
• Ensure interactions are acknowledged before command execution by deferring only when !interaction.deferred && !interaction.replied in the main handler (file: Discord/Bot/src/index.js).
• Hardened the interaction error path with a nested try/catch so response failures are logged and do not throw (file: Discord/Bot/src/index.js).
• Updated the execute handlers for /drop and /receive to call deferReply only when the interaction has not already been acknowledged (files: Discord/Bot/src/commands/drop.js, Discord/Bot/src/commands/receive.js).

Testing

• Ran node --check Discord/Bot/src/index.js and it succeeded.
• Ran node --check Discord/Bot/src/commands/drop.js and it succeeded.
• Ran node --check Discord/Bot/src/commands/receive.js and it succeeded.
