API Gap Implementation

[grandcamel]

I used Claude Opus 4.5 to analyze the gap in the MCP to API functionality. I then implemented ones we flagged as high and medium priority and fixed some minor logging issues.

Summary

• Add new tools for listing categories, accounts, scheduled transactions, months, and payees
• Implement bulk transaction operations (approve, delete, update)
• Add transaction retrieval with flexible filtering options
• Implement import transactions functionality
• Create error handling utility (getErrorMessage) for consistent error reporting across all tools
• Refactor CLAUDE.md for improved clarity and structure

Overall, love it! Just a couple questions about switching lines from "console.log" to "console.error". Pretty minor

I'll probably go ahead and merge as-is unless you happen to get to this in the next few days. I appreciate the contributions!

I see now. The "console.log" was actually resulting in an error.
