Pull request overview

This PR introduces several new utilities and configuration needed for “redeemer”/vault-related functionality in sw_utils, including a converter for OS token share/asset math, a new network config field, and new generic helpers for memoization and async batching.

Changes:

• Add OsTokenConverter (and tests) for converting between assets and shares using cached totals.
• Extend BaseNetworkConfig with META_VAULT_ID and populate it for all networks.
• Add memoize decorator (sync + async) and async_batched helper, and export new utilities from sw_utils.
