Display auction type and phase when querying auctions (#345)
* feat: differentiate auction types when queried

* feat: display auction type

* feat: add phase of collateral auctions

* fix: set reverse phase directly

* feat: revert base auction, use querying specifc structs

* fix: pass auction as interface to handlers

* set reverse phase on max bid (#348)

* Revert "set reverse phase on max bid (#348)" (#351)

This reverts commit 4b855250d529a4cbecb16d9d32b25ffeaffa3a68.

* fix: missing return

* fix: include collateral auction type

* fix: always include phase field for queries
