Remove unused `log` dependency and fix dependency ordering in log-ingestor/Cargo.toml

[coderabbitai]

Description

Two issues found in components/log-ingestor/Cargo.toml:

1. Unused dependency: The log = "0.4.29" dependency is not used anywhere in the log-ingestor codebase and should be removed.

2. Dependency ordering: The dependencies in the [dependencies] section are not alphabetically ordered. The dependencies should be sorted alphabetically for better maintainability.

Tasks

• Remove the unused log dependency from components/log-ingestor/Cargo.toml
• Reorder dependencies in the [dependencies] section alphabetically
• Run cargo check to verify no compilation errors
• Update Cargo.lock if needed
