captures the Azure error info if there is problem getting subscriptions.

Pull request overview

This PR enhances Azure subscription/environment detection diagnostics in cfa.cloudops.util by surfacing exception details during subscription listing and adding debug logging around subscription retrieval for check_ext_env().

Changes:

• Capture and print the caught exception in get_subscriptions() when subscription lookup fails.
• Add debug logging of retrieved subscriptions in check_ext_env() before checking for the EXT environment marker.

• This uses the root logger (logging.debug) and logs the full subscription name list, which may be sensitive and can be very noisy. Prefer the module logger and log only a count (or a small/redacted sample) at debug level.

    subs = get_subscriptions()
    logging.debug(f"Retrieved subscriptions: {subs}")
    return any("EXT-EDAV-CFA" in i for i in subs)

• Avoid eager f-string formatting and emitting full subscription names in logs. Even at DEBUG, logging the entire subscription list can be noisy and may expose environment/account details; parameterized logging also avoids unnecessary string building when DEBUG is disabled.

    subs = get_subscriptions()
    logger.debug(f"Retrieved subscriptions: {subs}")
    return any("EXT-EDAV-CFA" in i for i in subs)

I checked out this branch locally and successfully ran check_ext_env() without errors. Then I ran az account clear on a machine without an identity and reran and confirmed the stack trace shows the underlying azure error as a warning:

>>> from cfa.cloudops.util import check_ext_env
>>> check_ext_env()
True
>>> check_ext_env()
