FISH-9719 Implement Security filters to Suspend Usage When OpenAI API Max Count is Reached

[jGauravGupta]

Add IP Rate Limiting with Scheduled Cleanup

Description

• Introduced IP rate limiting for specific REST endpoints using JAX-RS filters.
• Configurable via MicroProfile Config (rate.limit (60), rate.time.window (1 Hour)).
• Utilized ManagedScheduledExecutorService for periodic cleanup of stale log entries.

Key Changes

1. Added IpRateLimitFilter to restrict Generative AI requests per IP.
2. Implemented scheduled cleanup to optimize memory usage.

How It Works

• Tracks API calls per IP in a ConcurrentHashMap.
• Blocks requests exceeding the limit within the configured time window.
• Periodic cleanup task removes outdated entries.

Tested locally.
The limit applies only to the ER diagram (app generation is filtered separately and differently)
One minor issue raised: when the user has reached the limit, and they make a new request to modify the diagram via AI, the pop up appears but the loading bar is visible in the background. The issue will be raised separately as it would require to design and modify the pop up used.
