fix(twilio): narrow classify() exception handling (SM-02)

[LakshnyaAdhikari]

Fixes #3506

Describe the changes you have made in this PR -

This PR narrows the broad except Exception: block in the Twilio classify() function.

• pydantic.ValidationError (expected for unconfigured/misconfigured environments) is caught separately and returns (None, None) silently.
• All other unexpected exceptions are now reported via the existing report_classify_failure helper (same pattern used by other integrations in this repo) instead of being silently swallowed.

Code Understanding and AI Usage

Did you use AI assistance (ChatGPT, Claude, Copilot, etc.) to write any part of this code?

• No, I wrote all the code myself
• Yes, I used AI assistance (continue below)

If you used AI assistance:

• I have reviewed every single line of the AI-generated code
• I can explain the purpose and logic of each function/component I added
• I have tested edge cases and understand how the code handles them
• I have modified the AI output to follow this project's coding standards and conventions

Explain your implementation approach:

• Problem solved: A broad except Exception in Twilio's classify() was silently swallowing all errors, including bugs and unexpected failures, not just expected misconfiguration.
• Alternatives considered: Letting non-ValidationError exceptions propagate instead of catching them — rejected because it would crash the discovery process instead of failing gracefully like other integrations.
• Choice of implementation: Splitting expected validation failures (silent) from unexpected failures (reported via report_classify_failure) matches the existing pattern used elsewhere in the repo.

Greptile Summary

This PR narrows Twilio integration classification error handling. The main changes are:

• Expected Pydantic validation failures still return no Twilio config.
• Unexpected classification exceptions are reported through the shared helper.
• The classifier still returns (None, None) after failures so discovery can continue.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
