Remove restriction to dengue for manually-triggered model runs (the only consequence is that the disease extent parameters are currently the same for all disease groups)
Various corrections
New policy for @Transactional on controller methods:
1. Only put it on write methods (not read-only). This avoids the restriction in step 2 for these methods.
2. Ensure that a @Transactional method calls another @Transactional method (e.g. a service), any exception thrown by the called method is allow to bubble up (or is rethrown). This avoids UnexpectedRollbackExceptions.
