Added description in appointment

[Copilot]

Pull request overview

This PR adds an optional free-text “description” to appointments and surfaces it through the booking flow and appointment cards, with a small UX tweak in the regular schedule modal and some comment translation.

Changes:

• Add description?: string to appointment types and persist it in MongoDB with a default value.
• Send/display the appointment description in the client booking flow and appointment cards, with a word-count validation helper.
• Show an alert when saving a regular schedule without changes.
