[refactor](trx-server): use trx-app for shared infrastructure

Replace server's local implementations with unified trx-app utilities.

Changes:
- Use trx_app::normalize_name() instead of local fn
- Depend on trx-app crate

This eliminates the server's copy of the normalize_name logic and ensures
both server and client use the same implementation.
