fix: resolve cherry-pick breakage and add missing modules

- Restore deleted module declarations (tutor, ugc_content_creator, user,
  user_role_profile, verification, video_editor) in db/models/mod.rs
- Add mod ai; to users/src/main.rs (fixes crate::ai import)
- Add pub mod ai_auto; to handlers/mod.rs
- Add rust_decimal dependency to payments/Cargo.toml
- Fix missing PgPool import in payments/src/ai_credits.rs
- Make LiteLLMUsage fields public in users/src/litellm.rs
- Add get_llm_base_url() and get_llm_model() helper functions
- Remove leading underscore from variables that are used

Partial fix for high-performance branch build issues.
