fix(journals): decouple IDB cache writes from API data return

QuotaExceededError on db_save was propagating through .then() into the
outer .catch(), which returned undefined and discarded the successfully-
fetched API data. Wrapped all db_save calls in try/catch so IDB failures
log a warning but never kill the load/create/update return value.

Also removed content_md_html and history_md_html from properties_to_save
— these are computed from content/history on every background refresh via
marked.parse(), so storing the rendered HTML alongside the source was
doubling storage cost per entry and the primary cause of quota exhaustion.

Affects: load, list, create, update, and qry functions in both journal
and journal_entry modules.
