feat: Enhance calendar filter with preset auto-detection and timezone fixes

[Naimul007A]

Enhances the calendar filter component with improved preset handling and timezone support.

Changes

• Custom Preset: Added a new "Custom" preset option that is automatically selected when dates don't match predefined ranges
• Auto-Detection: Implemented detectPreset() function to intelligently detect and highlight the active preset based on current date range
• Local Timezone: Changed date formatting to use local timezone (toLocaleDateString) instead of ISO format to prevent timezone conversion issues
• Initialization: Improved component initialization to properly set temporary dates and detect current preset on mount

Benefits

• Users can now see which preset is currently active
• Better handling of custom date ranges
• Eliminates timezone-related date shifting issues
• More intuitive user experience when switching between presets

Fixes #67

This pull request significantly upgrades the calendar filter component by adding a "Custom" preset for flexible date selection and implementing an intelligent auto-detection mechanism to highlight the active preset. Crucially, it resolves timezone-related discrepancies by ensuring dates are formatted according to the local timezone, leading to a more accurate and user-friendly date filtering experience.

Highlights

• Custom Preset Option: Introduced a 'Custom' preset that automatically activates when selected dates don't match predefined ranges, enhancing flexibility for users.
• Preset Auto-Detection: Added a detectPreset() function to intelligently identify and highlight the currently active date range preset based on the selected start and end dates.
• Timezone Fixes: Switched date formatting from ISO to toLocaleDateString to correctly handle local timezones and prevent date shifting issues, ensuring accurate date display.
• Improved Initialization: Enhanced the component's init() method to properly set temporary dates and detect the initial preset upon loading, providing a more consistent user experience.

Code Review

This pull request introduces useful enhancements to the calendar filter, including auto-detection of presets and fixes for timezone issues. The implementation is generally good, but I've identified a few areas for improvement to enhance correctness and maintainability.

My review includes feedback on:

• A potential issue with a duplicate key in the PHP presets array.
• A critical bug in the quarter_to_date preset detection logic, for which I've provided a fix.
• Unsafe date string parsing in JavaScript, which can lead to timezone-related errors. I've suggested a more robust approach.
• A minor code cleanup to remove commented-out code.

Addressing these points will make the component more robust and reliable. Thank you for the contribution!
