feature: categorize data (#36)

* feat: add FileId entity and change dbContext

* feat: change add-account API and add 2 APIs which handle categorized-get and categorized-delete for account

* feat: change add-transaction API and add 2 APIs which handle categorized-get and categorized-delete for transaction

* feat: add file-id-controller

* fix: fix unit-test
