instead of 'unable-to-process' sub folder, change to *alias-name*-log folder

[CraigWatt]

Need to consider this carefully first. Does this make 'more' sense for the end user?

Triage update (2026-03-23)

Status: Not implemented.

Evidence:

• unable_to_process is still the active error folder naming in mezzanine/source/profile code paths.

Recommendation: keep open if we still want a user-facing rename/migration plan.
