Reduce log level for repeated skip update messages

[Copilot]

Two log messages were emitting at INFO level every 10 seconds when no update was needed, creating log noise in production.

Changes

• Reduced "Check for updates!" from INFO to DEBUG in src/utils/data.rs
• Reduced "Last update was today. Skip update." from INFO to DEBUG in src/utils/update_type.rs

These messages now only appear when running with DEBUG logging enabled, while actual update operations continue logging at INFO level.
