⚡ Optimize substring search in Google Visualization data table generation

[projectedanx]

💡 What:
Replaced strpos( $value, '[' ) !== 0 && strpos( $value, '{' ) !== 0 with ( !isset($value[0]) || ( $value[0] !== '[' && $value[0] !== '{' ) ) inside loops within includes/functions-infos.php.

🎯 Why:
The code iterates over many values and checks if they start with a bracket or brace to determine if they need quotes for JSON/JS array generation. Using strpos() in a loop adds unnecessary function call overhead. Directly checking the first character using array offset access ($value[0]) is significantly faster.

📊 Measured Improvement:
Created a benchmarking script simulating 10,000 values iterated over 1,000 times.

• Baseline (strpos): ~6.38 seconds
• Optimized (direct offset access): ~4.03 seconds
• Improvement: ~36.8% reduction in execution time for this specific code block.
