Set up mix_gleam archive, gleam_stdlib, and gleeunit deps. Add Gleam compiler to all Dockerfiles, CI workflows, nix shell, and .tool-versions. Rewrite Numeric, QueryHelpers, and URLValidator from Elixir to Gleam with full ExUnit test coverage. Update all callers to use the Gleam modules directly via :towerops@module syntax. Remove duplicate sanitize_like/1 private functions in snmp.ex and trace.ex. Reviewed-on: graham/towerops-web#98
