Version 1.1.0

Added two new source types: videos and images, with automatic detection (YouTube/Vimeo and other video pages, plus direct image links and schema.org image data).
Added in-text citations in both parenthetical and narrative forms, each with its own copy button, following APA 7 rules (& vs. and, "et al." for three or more authors, "n.d." for missing dates).
Redesigned the popup with a cleaner, higher-contrast look. Copied references now keep their italics when pasted into Word or Google Docs.
