fix(cli): update default API base URL from instant.dev to api.instanode.dev

instant.dev was the retired pre-rebrand domain. Every CLI command (db new,
cache new, login, resources, etc.) was sending requests to instant.dev which
returns 404 for all API paths.

Change: APIBaseURL default "https://instant.dev" → "https://api.instanode.dev"

Also update all help text, Long descriptions, and comments that still
referenced instant.dev → instanode.dev:
  - cmd/root.go: Short, Long, login example line, APIBaseURL comment
  - cmd/login.go: Short (login), Long (login + upgrade)
  - cmd/discover.go: Long
  - internal/cliconfig/cliconfig.go: APIBaseURL field comment

The INSTANT_API_URL env var and ~/.instant-config api_base_url overrides
continue to work unchanged (they already take priority over the default).
