PhoenixKit V44 Migration: Rename DB Sync tables to Sync

This migration renames the DB Sync tables and indexes to match the module rename from DBSync to Sync.

Changes

Table Renames

• phoenix_kit_db_sync_connections → phoenix_kit_sync_connections
• phoenix_kit_db_sync_transfers → phoenix_kit_sync_transfers

Index Renames

All indexes are renamed to match the new table names.

Setting Key Renames

• db_sync_enabled → sync_enabled
• db_sync_incoming_mode → sync_incoming_mode
• db_sync_incoming_password → sync_incoming_password

Backwards Compatibility

This is a breaking change for existing installations. The migration handles the rename automatically, but any raw SQL queries referencing the old table names will need to be updated.
