Creates the sync tables if they don't already exist.

PhoenixKit's core migration system (V37, V44, V56, V58, V74) normally manages these tables. This module provides a fallback for installations where the tables haven't been created yet — every operation uses IF NOT EXISTS so it's safe to run even when tables already exist.

Usage

# In a migration file:
def up do
  PhoenixKitSync.Migration.up()
end

# Or with a schema prefix:
def up do
  PhoenixKitSync.Migration.up(prefix: "my_schema")
end

Tables Created

• phoenix_kit_sync_connections — permanent token-based connections
• phoenix_kit_sync_transfers — transfer history and approval workflow
