Change DEFAULT_LOCAL_DEV_MODEL_TYPE from "text-to-text" to "any-to-any"

[Copilot]

This PR addresses the FIXME comment in clarifai/utils/constants.py by changing the default local development model type from "text-to-text" to "any-to-any".

Changes Made

1. clarifai/utils/constants.py: Changed DEFAULT_LOCAL_DEV_MODEL_TYPE from "text-to-text" to "any-to-any" and removed the FIXME comment
2. clarifai/cli/model.py: Updated hardcoded default to use the constant instead of hardcoded "text-to-text"
3. clarifai/cli/templates/model_templates.py: Updated the default parameter in get_config_template() from "text-to-text" to "any-to-any"

Impact

• When users create new models via CLI without specifying a model type, they will now get "any-to-any" instead of "text-to-text"
• The change is minimal and non-breaking - existing code that explicitly specifies model types will continue to work
• Templates and configuration generation now consistently use "any-to-any" as the default

Before

DEFAULT_LOCAL_DEV_MODEL_TYPE = "text-to-text"  # FIXME comment indicated this should be any-to-any

After

DEFAULT_LOCAL_DEV_MODEL_TYPE = "any-to-any"

Fixes #679.
