disable stateful app detection

[adhami3310]

in cases where it's explicitly disabled but you are using state you might get:

TypeError: can't access property "$$typeof", Context is undefined

Greptile Summary

This PR changes how Reflex handles state detection by removing automatic state detection and introducing an explicit enable_state flag in the App class. Previously, Reflex would automatically detect if state was being used by analyzing components and event triggers. This automatic detection could sometimes conflict with explicit state configuration, leading to a TypeError (can't access property "$$typeof", Context is undefined) when state was explicitly disabled but still being used.

Key changes:

• Added enable_state boolean flag to App class (default: True)
• Removed automatic state detection during page compilation
• Modified state initialization to respect the explicit flag
• Updated tests to verify new state handling behavior

This change makes state handling more predictable by putting control in the developer's hands rather than relying on automatic detection.

Confidence score: 4/5

1. This PR is safe to merge as it improves predictability and fixes a TypeError.
2. High confidence due to comprehensive test coverage and clear logical improvements, though any change to core state handling requires careful attention.
3. The following files need attention:
   • reflex/app.py: Verify state initialization behavior
   • reflex/compiler/compiler.py: Ensure removal of state detection doesn't break edge cases
