Blockchain: get height of RingCT fork programmatically

Get height of the RingCT fork to start the output distributuon programmatically, instead of using a hardcoded index.

If using a hardcoded index, when the hardfork tables are modified, this can cause segmentation faults or horrific privacy issues: https://codeberg.org/wownero/wownero/issues/488#issuecomment-2514880.
