fix(web,ui): filter technical metadata from bookmark notes display

Add provenance line filtering to both sidebar BookmarkCard and
main BookmarkListItem components. Lines matching "TYPE from SOURCE"
pattern (e.g., "AUTHOR from OpenAlex Tags:") are now filtered out
alongside URL:, Title:, and Tags: prefixes. This ensures users only
see their actual notes, not internal metadata.
