fix(i18n): let generate-pot-file import hooks without a site

[mardausdennis]

generate-pot-file.yml has never completed successfully. It was added on 2026-08-08 and has run on 08-08, 08-09 and 08-16. All three runs failed the same way:

File "/home/runner/frappe-bench/apps/builder/builder/hooks.py", line 198, in <module>
    builder_path = frappe.conf.builder_path or "builder"
  File "/home/runner/frappe-bench/apps/frappe/frappe/utils/local.py", line 55, in _get_current_object
    raise RuntimeError("object is not bound") from None
RuntimeError: object is not bound

hooks.py reads frappe.conf at import time. That works wherever a site is bound, but bench generate-pot-file --app builder imports hooks without one, so the proxy raises before extraction starts.

The same workflow runs green in frappe/crm and frappe/lms, so a site-less import is the expected contract and the fix belongs in the app rather than in CI.

Scheduled runs fail quietly, so nothing surfaces this. builder/locale/main.pot was last updated by hand in #721 on 2026-08-13, not by the workflow. The roughly 190 strings wrapped in #746 and #750 are in the source but never reach the POT, so no language can translate them yet.

Behaviour is unchanged wherever a site is bound. Only the site-less import falls back to the default path.

Not runtime-tested: I have no bench here. The failing job log and the passing sibling workflows are the evidence I have.

Confidence Score: 5/5

The PR appears safe to merge with no actionable defects identified.

The fallback is limited to the unbound configuration proxy and retains the existing default route path.
