Added Export as .ics beside Export to PDF in Web Registration. Calendar export now uses USC's published term and session dates across years, excludes holidays and session breaks, preserves multiple meeting times and locations, and skips classes with TBA times. If required data cannot be validated, USC's official calendar exporter opens instead. Added host permissions for https://classes.usc.edu/ and https://www.usc.edu/ to retrieve public calendar metadata without sign-in credentials.

Improved optional SMS payment instructions with an exact $1 amount, a copyable eight-digit payment note, a prefilled Venmo link, and a section-specific QR code. Added payment-recovery guidance and a clearer secure-login path when a section is already watched. No new permissions or data-collection purposes.

Fixed a Firefox compatibility issue that could prevent class-notification requests from being submitted. Updated dependencies and release packaging. No new permissions, data types, or purposes.
