Follow-up pass for renaming Usage Ping/Data to Service Ping/Data

What does this MR do?

Related to #334569 (closed)

- usage_ping_or_data = /(usage)[ _-]?(?:ping|data)/i # Usage Ping, usage-ping, usage_ping, Usage Data...

We need to replace instances of usage_ping_or_data with "service". This MR handles the leftover instances that were not updated in the first passes. We are not renaming some backend services, and references to the database (and some generated HTML ids).

• Update FE symbol names
• Fix doc references to renamed files, as the old links threw 404s (e.g. app/services/submit_usage_ping_service.rb to app/services/service_ping/submit_service.rb)
• Update new doc references (redirects were working fine)
