Ice - new test and minor changes

[AgnieszkaMakulska]

• adding a test comparing results of lagrangian and bulk ice microphysics
• spectrum of ice_a and ice_c can be diagnosed
• rd_insol included in the "aerosol" dict

[Copilot]

Pull request overview

This PR extends the parcel-model ice workflow by (1) adding/adjusting long tests that compare Lagrangian vs bulk ice results and generate diagnostic plots, and (2) evolving the aerosol configuration to include rd_insol inside the aerosol JSON spec (plus a new depo toggle for depositional growth).

Changes:

• Require rd_insol inside each aerosol mode definition (update defaults + tests accordingly).
• Add depo option and wire it into the Lagrangian microphysics step.
• Add/adjust long tests and plotting outputs for warm/ice scheme comparisons; extend spectrum diagnostics to support drwt = ice_a/ice_c.
