fix(models): fix builtin provider detection and model matching (#120)

- Add glm-coding-plan to PROVIDER_ENV_MAP for proper env mapping
- Rename GLMCodingPlan value from 'glm' to 'glm-coding-plan' (kebab-case)
- Match custom providers against PROVIDER_PRESETS to reuse builtin models
- Fix provider key matching in create/update (use entry.name consistently)
- Clear stale base_url/api_key from config on provider create
- Clear model config when all providers are removed
- Add gateway restart on provider remove
