♻️ Refactor profile and session handling

- makes the profile access more efficient (replace in-app joins to a
  simple select query on profile table
- add partial support for access-tokens (still missing some RPC methods)
- move router definitions to specific modules and simplify the main http
  module definitions to simple includes
- simplifiy authentication code related to access-tokens and sessions
- normalize db parameters with proper namespaced props
- more work on convert all modules initialization to use proper specs
  with fully-qualified keyword config props
