Sync frontend configuration defaults with backend values

[imnotevelyn]

Hardcoded default values for guild configuration exist in React files like GuildConfigPage.js (e.g., slowmode, check intervals). If the backend changes, these defaults may become inconsistent.

Example Files:

• dashboard/src/pages/GuildConfigPage.js
• Backend config endpoint(s)

Recommended Actions:

• Fetch and sync defaults from the backend dynamically whenever possible.
• Document default value sources for maintainers.
