Add Ant messageContext to FidesUIProvider context

[jpople]

Description Of Changes

Adds messageContext to the FidesUIProvider so toasts are appropriately themed globally and the useMessage hook can be called more nicely.

Steps to Confirm

1. Test messages using Ant POC page or, for example, by modifying the groups on one or more systems on the system inventory
2. Messages should have Fides brand colors as in screenshot above

Greptile Overview

Greptile Summary

This PR refactors the Ant Design message API to use a centralized context provider pattern. The message.useMessage() hook is now called once in FidesUIProvider and the resulting messageApi is made available via a new useMessage() hook through React context.

Key changes:

• Added messageContext to FidesUIProvider with a custom useMessage hook for global toast theming
• Removed AntMessage export from fidesui package
• Refactored 40+ components to use the new useMessage() hook instead of local message.useMessage() calls
• Eliminated duplicate messageContext holders throughout the codebase
• Updated hook signatures to remove messageApi parameters (now accessed internally via useMessage())

Benefits:

• Consistent toast theming across the entire application
• Cleaner component code with fewer context holders to render
• Single source of truth for message API configuration
• Improved developer experience with simpler hook usage

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• This is a well-executed refactoring that follows React best practices. The changes are systematic and consistent across all files. The author fixed type errors and linting issues in follow-up commits. The pattern properly implements context with error handling, and all components correctly use the new hook. No breaking changes to functionality, just improved architecture.
• No files require special attention

Thanks for adding this developer improvements and updating the code everywhere. Code changes look good and the toasts work! I'll leave the approve and ask you just some small updates to make the PR complete: add DX entry in the changelog, update steps to reproduce with a way to test at least one of the toasts that was updated.
