Improve errors thrown by the server

Another stepping stone in the grand scheme of #267 (closed).

Fixes #286 (closed) (where #289 keeps track of the full resolving of the issue).

This MR is a WIP effort to convert the instances of panic/error in the codebase in either proper exceptions (if thrown by effectful code) or use a trick similar to what I have done here with fromDBid to have a proper stacktrace attached.

This will allow us to have a top-level handler in the server that will rewrap these into proper BackendInternalError and thus reuse the FrontendError framework that we implemented.
