Subject: [PATCH] cmd/geth: exit when freezer has legacy receipts (#24943)

In #24028 we flagged a warning when finding legacy receipts in the freezer. This PR nudges users a bit more strongly by preventing geth from starting in this case until receipts have been migrated.

It also adds a flag --ignore-legacy-receipts which when present allows geth to start normally.
