Timestamp-related improvements and gallery and video viewing history in the landscape app

This update mainly concerns the landscape app, along with improvements and BUG fixes in EFV Advanced. The main changes I remember are listed below; some smaller changes are not listed.

EFV updates

1. Adaptive M3U8 timestamp protection now supports request-count limits. The assembled URL becomes invalid immediately after 1 or n requests.
2. Added a random-segment-naming switch. When enabled, segments receive random names.
3. Added mp4 download collection to the MacCMS cms collection api. Retained transcoded mp4 files can be supplied to the MacCMS cms downloader.
4. Improved video-management statistics. Filtering by a category now shows that category's own total video count, successful processing count and related statistics.
5. Various feature and detail improvements.

APP updates

1. Rewrote the api systems for the landscape and portrait app versions to maximize speed and concurrency.
2. Added a video viewing-history page to the landscape app, displaying all history with infinite scrolling.
3. Added gallery page-position history to the landscape app, displaying viewing records. Reopening a gallery prompts you to continue from the last viewed page; confirming resumes from the saved position.
4. Added configurable announcement text to the landscape app payment page, set directly in the administration interface.
5. Added password reset to the landscape app, making it easy for users to reset their passwords.
6. Added a confirmation dialog when signing out in the landscape app, preventing accidental taps.
7. Added image-server switching to the landscape app. Configure multiple image CDN services so users can switch between them in their account center.
