fix: Track all dEURO mints including CoW Protocol swaps (#54)

[bernd2022]

• fix: Track all dEURO mints including CoW Protocol swaps

• Add getRecentMints() method to query all mints from Ponder
• Extend Telegram service to send notifications for all significant mints
• Use correct Ponder GraphQL syntax without where clause filtering
• Add chain-specific transaction explorer URLs

This ensures all dEURO mints trigger social media notifications, not just those with MintingUpdateV2 events.

• chore: Remove unnecessary package-lock.json and restore yarn.lock

• fix: Prevent duplicate notifications and improve error handling

• Add duplicate detection to avoid sending same mint twice
• Track MintingUpdateV2 txHashes to filter them from general mints
• Add try/catch for error handling when fetching mints
• Increase query limit from 100 to 500 to handle more mints
• Use earlier timestamp between generalMints and mintingUpdates to avoid gaps

• fix: Critical bugs in mint notification system

• Fix initial timestamp bug: Use current time instead of future time for mint tracking
• Improve duplicate detection: Check txHash existence before processing
• Simplify timestamp logic: Remove problematic Math.min() that caused missed mints
• Add proper txHash validation before using in URLs
• Clean up filter logic for better readability

• fix: Prevent notification spam on restart and limit batch size

• Initialize mint tracking from 1 hour ago instead of current time
• Prevents duplicate notifications after API restart/deployment
• Add MAX_NOTIFICATIONS limit (10) per update cycle to prevent spam
• Log warning when notification limit is reached
• Balances between catching recent mints and avoiding notification floods

• fix: Simplify notification message - remove unnecessary URL construction

• Remove chain-specific URL logic (dEURO only exists on Polygon)
• Display txHash directly in message instead of constructing URLs
• Simpler and cleaner notification format

• fix: Remove unnecessary complexity from mint tracking

• Reduce query limit from 500 to 50 (sufficient for regular updates)
• Remove unused fields from query (id, blockheight)
• Start tracking from current time instead of 1 hour ago
• Simplifies implementation without affecting functionality

• fix: Radically simplify mint tracking implementation

• Remove all duplicate detection logic (accept occasional duplicates)
• Remove separate generalMints timestamp tracking
• Remove MAX_NOTIFICATIONS limit and logging
• Remove try-catch and error handling
• Remove txHash from types and queries
• Simplify getRecentMints to minimal implementation
• Reuse existing mintingUpdates timestamp for all mints

From 106 lines to ~25 lines of actual new code

• feat: Adapt to the existing implementation
