TokenDao: Export as default alongside TokenData

Our coding standards are to create a separate file for classes and
interfaces, but this is a bit different: this "interface" is more like a
struct, and it's used to define the return type of a method of this
class.  Since it's inherently coupled, I'm keeping it in the same file.

The idea is that the caller will provide its own abstraction rather than
continuing to export this one.  Note that Typescript does support
re-exporting symbols if need be.

* src/server/daemon/controller.js: Adjust import of TokenDao (TS compiles
  default modules as `default').
* src/server/service/TokenedService.js: Adjust import of TokenDao.
* src/server/token/TokenDao.ts: Export TokenDao as `default'.  Export
  TokenData.
* test/server/token/TokenDaoTest.ts: Adjust import of TokenDao.  Import
  TokenData.
