clean service counters and env counters when deleting project

[Cynthia-0203]

What this PR does / Why we need it:

Previously, env service version counters and service template revision counters could remain in the counter collection after project deletion. If a project with the same name was recreated later, these stale counters could affect newly created resources by continuing revisions from deleted project data.

What is changed and how it works?

Delete env service version counters after env service versions are removed for the project.
Delete normal and production service template revision counters during async project resource cleanup.

Does this PR introduce a user-facing change?

• API change
• database schema change
• upgrade assistant change
• change in non-functional attributes such as efficiency or availability
• fix of a previous issue
