Bulk task updates currently send English notification subjects and failure reasons in French sessions. Translate success/failure subjects, all four access/configuration failure reasons, and the shared task-count prefix (“Pour 1 tâche” / “Pour 6 tâches”). Preserve task links, update behavior, and non-task notification formatting.

Validation in the local Apple-container Rails portal, English and French:

• Exercised the actual bulk-update controller’s background branch for success and all four failure reasons, with task mutations and process spawning stubbed. Checked generated headers, reasons, counts, and task links.
• Checked singular/plural task counts and compared non-task helper output with the original formatting in both locales.
• Desktop Chromium: opened the generated notifications in the live portal and expanded their details; subjects, reasons, counts and links passed, with no JavaScript errors.
• Test messages were sent only to a disposable local QA account, with email disabled; the account and messages were removed afterward. No real task updates or processing jobs were run.
• git diff --check passed; trial merge with [ADD] errors in I18n format #1677 at 0067e3e was clean.

Related to #1660. Independent branch based on dev; no validation-message keys overlap #1677.

There is a bug in the PR, see comment.

This is a mistake. The original code would log messages with a prefix that depends on the type of the first object in success_list, which could be any CBRAIN object. This was done by line 31 in the original code which said

type   = generic_human_type(success_list.first)

So we got messages like "For 3 files" or "For 5 users" or "For 7 tasks".

But this PR has hardcoded that the messages now always say "tasks". which will be very misleading when the list is not tasks.

Thanks Pierre — agreed that this shared helper must preserve the object type. That distinction is retained in the extracted message_count_prefix helper near the bottom of the file:

def message_count_prefix(objects)
  return I18n.t('task_message_helpers.for_tasks', :count => objects.size) if objects.first.is_a?(CbrainTask)
  "For #{view_pluralize(objects.size, generic_human_type(objects.first))}"
end

The translated task wording is used only when the first object is a CbrainTask. For files, users, and other non-task objects, the fallback still calls generic_human_type and view_pluralize, preserving the original wording such as “For 3 files” or “For 5 users”. Both the notice and error helpers call this method.

The English/French checks also compared non-task helper output against the original formatting. Non-task prefixes intentionally remain in their original English wording in this task-specific PR.

@dlq You're absolutely right, I didn't see the handling of the object types in there. All good.
