feat: use prefix variable for POWERTOOLS_SERVICE_NAME in Lambda functions (#4948)

Updates `POWERTOOLS_SERVICE_NAME` to use the `prefix` variable instead
of hardcoded values in pool, ami-housekeeper, scale-down, scale-up,
webhook and dispatcher Lambda functions.

## Why
- function names already include prefix, `POWERTOOLS_SERVICE_NAME`
should too
