Handle undefined OAuth token pools gracefully

[AntoineKM]

Hi @harlan-zw,

Description

What did I change?

• Modified the initialization of tokens and privateTokens in nuxt.config.ts - Now initializing as empty arrays ([]) instead of false when environment variables are not set.
• Updated the condition for seeding main tokens - Now checks if the tokens array is empty (tokens.length === 0) instead of checking if it's falsy.
• Left the rest of the Nuxt configuration unchanged.

Why did I change it?

• To fix a runtime error: "privateTokens.map is not a function - This error occurred because privateTokens was sometimes false instead of an array.
• To improve the robustness of the OAuth token handling: The code now gracefully handles cases where the OAuth pool environment variables are not set.
• To ensure consistent behavior: By always working with arrays (even if empty), we prevent type-related errors and make the code more predictable.
• To maintain functionality when environment variables are not set: The changes allow the application to run without errors, even if the OAuth pools are not configured, potentially falling back to default behavior.
