Subject: [PATCH 1/3] fix(portuguese/tsundoku): parse DD/MM/YYYY chapter dates

The site now shows chapter release dates as DD/MM/YYYY (e.g. "17/07/2024").
parseDate expected "month day, year" text, so the split produced undefined
parts and dayjs(...).toISOString() threw "Invalid time value", failing
parseNovel on every novel.

parseDate now reads DD/MM/YYYY, still accepts the older month-name layout,
and returns null for a missing or unrecognised date instead of throwing.
Version 1.0.1 -> 1.0.2.
