log: serve localized content from the HTMX endpoints

Browse source 
The /log page renders its content asynchronously by hitting
/api/log/latest?as=html and /api/log/by-date/{day}?as=html via HTMX.
Both endpoints returned StrategicLog.content (English) verbatim,
ignoring the new StrategicLogTranslation table entirely. The
_resolve_log_content helper I added to pages.py earlier was wired
into the page handlers themselves but never reached for HTMX swaps,
so Italian users only ever saw English content despite their
lang='it' preference being persisted and translations being
generated correctly.

Fix: add a _localized_content helper in api.py that looks up the
matching translation row for the requesting principal's lang.
_log_partial_payload gains a content_override arg; both HTMX
endpoints (log_latest, log_by_date) compute the override and pass
it through. JSON paths (?as= other than html) remain English to
avoid changing the public API contract.
