Subject: [PATCH] feat(Bangumi_Topic_Share): multiple fixes and improvements,
 bump version to 6.1

- NSFW episode fallback: parse h2.title for ep number/name, extract subject from DOM
- Fix share button incorrectly inserted into #timeline items
- Fix AI config section right padding too wide
- Open OAuth auth in centered popup window instead of new tab
- Fix strikethrough not visible in card screenshot (iframe CSS override)
- Limit card content images to 3, show omitted count tip
