chore: refresh SUGGESTED_MODELS for all providers

Updates the SUGGESTED_MODELS quick-add list in lib/types/model-config.ts
against each provider's official model docs as of 2026-06-09.

- openai: GPT-5.5 / 5.4 frontier; drop deprecated 5.0-5.2 family
- anthropic: add Opus 4.8/4.7/4.6, Sonnet 4.6, Haiku 4.5 (new dateless
  pinned IDs); fix wrong date suffixes on Opus/Sonnet 4.5
- google / vertexai: adopt Gemini 3 family; drop Gemini 2.0 (shut down)
  and 1.5
- azure: GPT-5.x line + o3 / o4-mini; drop gpt-4-turbo / gpt-35-turbo
- bedrock: Opus 4.8/4.7/4.6, Sonnet 4.6, Haiku 4.5, Nova Premier /
  Nova 2 Lite, Llama 4 Maverick / Scout, Mistral Large 3, Pixtral
- openrouter: refreshed against live /api/v1/models
- deepseek: V4 Pro / Flash
- siliconflow / modelscope: DeepSeek V4, Qwen 3.x, drop bogus
  qwen3.5-plus
- gateway: verified against live Vercel AI Gateway endpoint
- doubao: Seed 2.0 / 1.8 / 1.6 in official dash-form IDs
- minimax: + M2.5
- novita: M3, GLM-5.1, Kimi-K2.6, DeepSeek V4
