v1.4 Test - DB Sync Init Script

Test Build — Do Not Use as Daily Driver

This is a test firmware for validating the SD card database sync feature.

What's Being Tested

A new init script S91_db_sync that runs at boot between SD card mount and
hiby_player startup. If a usrlocal_media.db file is found on the SD card
root it will be copied to internal storage and deleted from the SD card.

This enables PC-side database generation — place a pre-built database on the
SD card and it will be picked up automatically on next boot.

Also includes

• Joliet and Rock Ridge ISO extensions for better cross-platform compatibility
• All v1.3 modifications (Unified Theme, sorting patch, Unicode font, ADB support)
