23 Donation e2e integration and controller unit testing (#28)

* E2E test stubs

* feat: donations controller impl

* Some failure tests, adding supertest and expanding jest.config.ts to recognize tests in /test folder

* SqLite setup and longer setup timeout

* Using enums, testing for umbrella db throws error, GET cases if db is empty

* Passing success tests

* Test cases for missing responses and expanded DTO validation

* reformatting

* Fixed DTO field test

* Removing unnecessary cases

* Changed wording to be clearer

* validation to match real service behavior

* Rename donations.e2e-spec.ts to donations.controller.spec.ts

* Tests pass e2e without db state check or cleanup yet

* Tests don't actually pass e2e,  no db state check or cleanup yet

* Temporary logging, using actual db

* Database entry validation, uses donation transactions

* Removing console.logs and moving most of the donation with mock tests into donation.spec.ts

* Fix for created at, may reduce performance(?)

* Fix for returning non-anonymous donations

* New migration created for int amount

* Defaulting createdAt and updatedAt , tests pass

* change test DB creds and add environment variables
