Add GPT-6.1 Sol as the default catalog model (#49318)

Add `gpt-6.1-sol` to the bundled model catalog with its capabilities, reasoning levels, and availability message. Give it the highest catalog priority and update older Sol descriptions to reflect their generations. Update startup, model picker, and tool catalog snapshots to reflect the new default and catalog contents. GitOrigin-RevId: 1092a0524c6d1813ddd600c31c4fd0e708294ae9
