refactor(web/converse): Refactor first handlers to rouille
This commit starts the refactoring process towards dropping actix (and tokio, ...). It builds, but at this commit, Converse does *not* work. I decided to commit to avoid more ridiculous diffs. Included changes: * Added dependency on rouille. * Refactored DbExecutor (formerly actix actor) to simply be a type with a few methods. Most actor messages still exist as they are being referred to by handlers. * Started refactoring two of the handlers (and their related renderer functions) into Rouille's call scheme. Important note: Rouille does not have safe session management out of the box, and it will need to be implemented as this progresses.
