📄 Description

This PR fixes the confusing time display issue in graphs where minutes were shown in 12-hour format without AM/PM indicators, while hours were correctly displayed in 24-hour format.

Problem

The issue occurred when D3.js default tickFormat() method mixed 12-hour and 24-hour time formats, creating confusing sequences like:

"8:45", "21", "9:15" (mixing 12-hour minutes with 24-hour hours)
"08:45", "09 PM", "09:15" (inconsistent format)

Solution

Implemented a custom 24-hour time formatter that replaces D3's default x.tickFormat() in both graphs.server.js and graphs.zone.js:

// Custom 24-hour time formatter to avoid 12-hour format in minute displays
function custom24HourFormatter() {
    var formatMinute = d3.utcFormat("%H:%M"),  // Always use 24-hour format
        formatHour = d3.utcFormat("%H");       // Always use 24-hour format
    // ... other format handlers
    
    return function(date) {
        // Logic to choose appropriate format based on precision needed
    };
}

Result

Time displays are now consistent with 24-hour format throughout:

✅ "08:45", "21", "09:15" (consistent 24-hour format)
✅ "20:45", "21", "21:15" (proper progression)

Changes

Modified: docs/shared/static/js/graphs.server.js - Added custom formatter for server graphs
Modified: docs/shared/static/js/graphs.zone.js - Added custom formatter for zone graphs
Compatibility: Uses ES5-compatible syntax for broader browser support
Scope: Minimal changes (8 lines modified per file) affecting only time formatting

Testing

✅ Verified syntax with Node.js and JSHint
✅ Tested problematic time sequences that caused the original issue
✅ Confirmed fix works for both server and zone graph views
✅ Maintains all existing graph functionality

Fixes #216.
