Version 1.1 adds attendance percentage support to the UCAM attendance summary page. Each course now shows the present percentage beside the present count, calculated from present and absent class totals.

Changes:
- Added present percentage badges for attendance courses.
- Badges turn red when present attendance is below 85%.
- Badges stay green when present attendance is 85% or higher.
- Courses with no recorded classes yet do not show a percentage badge.
- Updated extension metadata and Mozilla submission icons.
