Pull request overview

Implements the “simple” radiation framework (Vallis et al., 2018) with optional idealized solar insolation (Issue #544, #533), updates model wiring to provide surface albedo to radiation, and refreshes related test/case configurations and outputs.

Changes:

• Replaces the prior gray-radiation implementation with a new simplified radiation module supporting Gray and LW(2-band)+SW(1-band) options, including surface SW/LW up/down flux outputs.
• Introduces a simple solar insolation module and hooks it into the atmospheric radiation component.
• Refactors topography reading into a shared mesh method and updates test case configs/scripts accordingly.
