backend dotenv

[jpandersen87]

This PR is a quality of life improvement to how environment variables are handled for local gradle tasks (these variables are NOT used in the prime-router application being built when it is ran).

• All environment variables from docker yaml and gradle build moved to .env file
  • host-specific overrides that are used in gradle build have a host (capitalization depending on existing pattern) prefix
• build fun loadDotEnv added
  • creates map variable of the following in priority least to greatest:
    • .env
    • .env.local
    • host environment
    • project properties
  • applies specific overrides (docker hostname to localhost) to particular variables if one wasn't supplied manually via host environment or project properties
• build vault fun updated to create new map (applying vault variables on top) from provided map
• env var accesses replaced with dotEnv
• Prime-router .gitignore initialized using the root .gitignore
  • Entry ignoring .env.local / .env.*.local files added to .gitignore
• prime-router specific .gitignore entries removed from root .gitignore
• docker compose usages across github actions, un-deprecated documentation, scripts, etc. updated to use dotenv file
