attack meta changes (#742)

## Description: 
Full changes for the attack meta for v23. These include changes to
attack losses and speed both in general and in relation with defense
posts and fallout. Max population, population growth, and gold
generation are also adjusted. Troops and attack boats sent now count
within max pop. Deployed at attackmeta.openfront.dev

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [x] I understand that submitting code with bugs that could have been
caught through manual testing blocks releases and new features for all
contributors

regression is found:
