PR Summary

Medium Risk
Introduces a new on-read migration path for persisted headers records and bumps the blocks storage version; mistakes could prevent opening or reading existing databases until resynced.

Overview
Adds a generic VersionWrapper/Migratable mechanism for versioned DB values (no longer test-only), enabling automatic migration when deserializing older records.

Implements a v0→v1 migrator for StorageBlockHeader (handling the new fee_proposal_fri field by defaulting to None) and adds deprecated v0 header type + serialization/test-instance support.

Switches the headers table to VersionWrapper<StorageBlockHeader, 1> and bumps STORAGE_VERSION_BLOCKS from 6.0 to 6.1 to reflect the migratable blocks-format change.

            CURRENT_VERSION.. => {
                error!(
                    "Unable to migrate stored header from version {} to current version.",

The message here should make it clear that the problem is in the version number
Maybe something like "Version {} is >= current version. Can't migrate"
