Subject: [PATCH] Prevent internal RPC error leakage

Replaced instances of message.reply(err.message) with a generic user-facing
error string.
Appended .catch(console.error) to discord API replies.
Logged actual error instances internally with console.error.

+## 2024-06-07 - Prevent internal RPC error leakage
+**Vulnerability:** The tipbot leaked internal bitcoind-rpc error messages to users via Discord API `message.reply(err.message)`.
+**Learning:** Returning unhandled or raw errors directly to the user is a security vulnerability, as it might disclose sensitive system information, paths, or connection issues in production. Unhandled promise rejections can also crash the entire process.
+**Prevention:** Always log the `err` object internally with `console.error(err)` and replace the raw message sent to users with a sanitized, generic message such as 'An internal error occurred while processing your request.' Always use `.catch()` on async functions returning a promise like Discord API calls to prevent unhandled rejection crashes.
