Define the deployment transaction fee model

deployment fee:
1/4 of base fee for worker process + 1/10 of base fee for each trigger

The issue only states the deployment fee formula: one quarter of the base fee for the worker process and one tenth for each trigger. Start by locating the deployment transaction fee calculation and the worker and trigger handling, then confirm the intended behavior and tests before changing anything. Done means the fee model is defined, implemented, and verified for deployments with the relevant worker and trigger counts.
