feat(providers): upgrade DouBaoSeed preset to Doubao Seed 2.1 Pro

Point DouBaoSeed at doubao-seed-2-1-pro across all six clients (claude, claude-desktop, codex, opencode, openclaw, hermes), replacing doubao-seed-2-0-code-preview-latest. Sync display names to "Doubao Seed 2.1 Pro" and correct the openclaw cost field (0.002/0.006 -> 0.84/4.2 USD/1M) to match the new model.
