Availability windows were stored and served as a single bookable row, so a
9:00 AM-4:00 PM window showed to students as one giant slot and booking it
consumed the whole day; past and multi-day windows also leaked into the
booking page as nonsense entries.
- Split windows into consecutive lesson-length slots on save (REST and admin
form); each chunk is independently bookable and weekly recurrence creates a
series per chunk so "reserve this time weekly" holds the same hour each week
- Reject windows spanning multiple days or shorter than the lesson length
(400 invalid_window)
- Never return slots whose start has passed from GET /availability
- Migrate pre-split rows: Plugin::boot re-runs the Installer on version change
and AvailabilityRepository::splitOversizedWindows() rewrites unbooked
same-day oversized windows in place
- Display all times in 12-hour AM/PM form (booking page, wp-admin lists,
editor previews)
- Add a List | Week view toggle to the student booking page and the
instructor availability page, with previous/next-week navigation honouring
the site's start_of_week option (new WeekCalendar helper)
