The scanner no longer assumes courses sit at a fixed depth. It walks
each branch and marks a folder is_course when it holds media directly
or its children read as chapters (01_, 1. , Module 2, Week 3);
everything above that is a category, and every folder still gets a
course_id pointing at its nearest course for cheap rollups. An empty
.course/.category marker file overrides the heuristic per folder.
Also:
- Roll up progress for the whole library in two grouped queries
instead of one prefix-matched query per course/folder card.
- Store folders/videos/quizzes paths as utf8mb4_bin so folders that
differ only in case (CCNP Notes vs CCNP NOtes) aren't merged by a
case-insensitive UNIQUE key.
- migrateLibrarySchema() brings an older install's tables up to date
at scan time, so there's no separate migration step.
- Library UI gains a categories view alongside shelves/catalog; the
continue-watching strip's play button now seeks to the saved
position on open.

Course cards go back to the colour-block art that previously sat under the
captured frame, so the UI is unchanged apart from losing the photo.
- Drop thumb.php, generateThumbnails(), captureThumbnail() and
ensureThumbnailColumns(), plus the first-video tracking the scanner only
kept to pick a frame source.
- Drop the ffprobe fallback in probeDuration(); the pure-PHP mvhd parse is
now the only scan-time probe, with the player's report on first play as
the remaining fallback.
- Drop THUMBNAILS_DIR/THUMBNAIL_SEEK_PERCENT from config, the
thumbnail_* columns from schema.sql, the thumbnail counters from scan
output, .thumb img from the stylesheet, and the matching README parts.
Existing databases keep two now-unused folders.thumbnail_* columns; they
are inert and can be dropped by hand if wanted.

Scanner indexes quiz files found next to videos ([&] questions, "- "
options, "-- Correct" markers; _notsolved twins ignored). Quizzes appear
in the folder content list interleaved with videos by filename order.
New api/quiz.php serves questions without answers and grades attempts
server-side; per-user best/last score and attempts stored in
quiz_progress. Folder/course progress now aggregates videos + quizzes
with partial credit for partial scores.
