Indexer Queries needed for new functionality

- [x] Modules by modification time, allows for historical code data
- [ ] Transactions by coin type and owner, with full information, allows for all coin transactions for a user
- [x] Coin / FA Refs, tells if a coin can be minted or burned or frozen or dispatchable
- [x] Object refs, tells if an object can be transferred, or deleted, or extended

The issue identifies indexer queries for modules, Coin/FA refs, and object refs, with transactions by coin type and owner still unchecked. Start by locating the existing indexer-query entry points for the completed items and determine where the missing transaction query belongs. Done means it returns full coin-transaction information filtered by coin type and owner.
