theme_boost_o365teams: Remove dead core_course_renderer overrides

[Lai Wei (weilai-irl)]

course_section_cm() and course_section_cm_name_title() no longer exist in the Moodle core course renderer, so the overrides were never called.

🟡 Changes recommended

The renderer file is removed without the decimal version bump in version.php that this repo's plugins apply for code-change PRs, so caches/upgrade won't be triggered to reflect the removal.

What changed in this PR

This PR removes dead code from the theme_boost_o365teams theme. It deletes the theme_boost_o365teams_core_course_renderer class (which overrode course_section_cm() and course_section_cm_name_title()) and the corresponding require_once in renderers.php. Because recent Moodle core no longer calls these core_course_renderer methods, the overrides were never executed, so removing them has no functional impact. I confirmed there are no remaining references to the removed class, file, or methods anywhere in the repository, and the theme's renderer auto-discovery (theme_overridden_renderer_factory in config.php) will simply fall back to the core renderer.

Changes:

• Delete the unused classes/core_course_renderer.php renderer override file.
• Remove the now-dangling require_once of that file from renderers.php.

File	Description
theme/​boost_o365teams/​renderers.php	Removes the require_once for the deleted renderer so no dangling include remains.
theme/​boost_o365teams/​classes/​core_course_renderer.php	Deletes the dead renderer override class that core no longer invokes.
