Add OverrideIndex property to SignalStreckenZuordnung table.

This migration adds a new "OverrideIndex" column to the "SignalStreckenZuordnung" table, allowing for manual ordering of signals within a track configuration. The column is nullable and stores an integer value representing the override index. This enables more flexible control over signal placement beyond the default sorting logic.
