chore(iast): fix iast pytest collection error

[avara1986]

What Does This Do?

This PR continues the work of the following PRs
#15175
#15141

Fixes a bug where IAST's post_preload() function drops the inspect module from sys.modules, causing pytest's test collection phase to fail with signature introspection errors

Motivation

When IAST is enabled and post_preload() drops the inspect module from memory, pytest encounters errors during test collection:

ERROR collecting
unexpected object <Signature (self, enabled, clieny, client, mock_client, session_user)> in __signature__ attribute

Could not determine arguments of <function test_get_user at XXX>:
unexpected object <Signature> in __signature__ attribute

Root Cause

The issue occurs because:

1. Pytest imports inspect early and creates Signature objects during its initialization
2. IAST's post_preload() removes inspect from sys.modules to avoid Gevent conflicts
3. Pytest reimports inspect when it continues to use inspect functions
4. Type/identity checks fail because the Signature class from the old module doesn't match the new one

This is a module identity mismatch problem: old_inspect.Signature ≠ new_inspect.Signature

When pytest tries to validate signatures with isinstance(sig, inspect.Signature), it fails because the signature object's class is from the old (deleted) module, but inspect.Signature refers to the class from the new (reimported) module.

Gevent Compatibility Note

While the original implementation dropped inspect to prevent Gevent conflicts, this created a worse problem by breaking pytest entirely.

Trade-off Decision:

• Pytest compatibility is critical for developers (breaks all testing)
• Gevent timeout issues (if they occur with inspect) are rare and workaroundable
• Breaking all pytest collection is not acceptable

If Gevent issues resurface with the inspect module, they should be addressed through:

1. Local imports of inspect within IAST functions (as originally intended)
2. Documentation for Gevent users
3. Alternative approaches that don't break pytest
