Refactor toolbar buttons across various pages to unify styling

- Updated button classes for consistency in the playersoftware-page, playlist-page, resolution-page, schedule-page, settings-page, syncgroup-page, tag-page, task-page, template-page, transition-page, user-page, and usergroup-page.
- Removed unnecessary text from button titles and ensured all buttons have the 'ots-toolbar-btn' class for uniformity.
- Cleaned up the code by removing commented-out sections and ensuring proper indentation.
