Refactor: Use symbolic constants for volume header magic numbers (#1525)

Browse Source 
Replaced hardcoded 0x56455241 ('VERA') with TC_HEADER_MAGIC for better readability and maintainability.
Also replaced 0x5645524142455854 with TC_BOOT_DRIVE_FILTER_EXTENSION_MAGIC and added 'ULL' suffix for 64-bit safety.
