fix: RTL support for timelines and header dropdown

- InteractiveTimeline: dir="ltr" on scroll area, i18n for all strings
- ArtefactVersionTimeline: text-start, ms-11 logical properties
- Header dropdown: end-0 instead of right-0, text-start on menu items
- Added 11 new timeline i18n keys (en + ar)
