Update Claude model lineup

[anubissbe]

Summary

• replace the Anthropic model constants with the new Sonnet 4.5, Opus 4.1, Haiku 4.5, and Opus Plan Mode identifiers
• update allowed model handling across the agent registry, CLI, pricing defaults, and analytics scripts to match the refreshed lineup
• refresh dashboard chart colour mappings so the new model short names render consistently

Testing

• bun run lint (fails: 403 when downloading biome)
• bun run typecheck (fails: missing bun-types definitions in the environment)
• bun run format (fails: 403 when downloading biome)
