Description

Summary of Work

This pull request consolidates improvements to the Koii Network task funding Slack integration, focusing on:

1. Security Enhancements

• Robust Slack request verification

• Support for both standard and KPL (Koii Participation Layer) task funding
• Detailed error logging and user feedback

3. Code Quality and Maintainability

• Improved error handling in funding functions

• Created separate funding methods for standard and KPL tasks
• Enhanced error handling with detailed Slack response messages
• Improved logging of funding attempts and results
• Standardized environment variable usage for keypair and secrets

Tests and Verification

Verification steps:

1. Test Slack request signature verification
2. Validate user authorization workflow
3. Test both standard and KPL task funding scenarios
4. Verify error handling and Slack response mechanisms
5. Check environment variable loading and usage
6. Ensure no sensitive information is exposed in logs
