Storage had to be reshuffled to facilitate iteration over all token IDs for a specific metadata.

Scoped out for a new task:

• Update price method + tests (issue)
• Update minters allowlist method + tests (issue)

This will require indexer changes. Note that metadata ID for creating metadata has been changed from u64 to U64 in case that third parties want to use JS indexers to index Mintbase.
