Make some APIs more flexible and fix corner-case encoding bugs

[SpaceManiac]

• Fix possible crash in presync on second run due to passing network name where caip2 is expected.
• Allow getRelatedWallets to accept any IDatabaseConnection, not just PoolClient.
• Make ERC721 primitive scheduledPrefix optional in case a game doesn't need to react to mint events.
• Fix middleware buildQuery helper not escaping values; e.g. {"a": "b&c=d"} now properly round-trips.
• Fix snapshots not saving if DB password contains special characters.
• Fix getAdjustedHeight for emulated block mode always infinite looping.
• Use toLowerCase instead of toLocaleLowerCase on wallet addresses to avoid theoretical problems if a server is ever run in Turkish locale.
• Attempt to fix inconsistent CJS/ESM incompatibility issues with mina-signer by upgrading to a version that has native ESM support.
• Tweak setAchievementProgress to keep existing completed_date if set.
