🚀 Enhanced ESX Core Cron Task Handling

Description:
This commit brings substantial enhancements to the time handling functionality in the 'esx_core/[core]/cron/server/main.lua' script for the FiveM server:

- Utilized Unix Timestamps: Replaced the existing `GetTime()` function with `GetUnixTimestamp()`, ensuring precise time representation by using the Unix timestamp format (seconds since January 1, 1970). This change mitigates potential issues related to Daylight Saving Time (DST) transitions.

- Refined Task Execution Logic: The `OnTime` function has been refactored to operate based on Unix timestamps, ensuring accurate execution of scheduled tasks without any inconsistencies due to local time conversions.

By introducing these improvements, the cron-like system now operates with enhanced accuracy, bolstering the stability and predictability of scheduled events on the FiveM server. Extensive testing has been conducted to guarantee compatibility with various server environments.
