fix: combine session image and text into single Telegram message

When creating a session with an image, send it as a single SendPhoto with the schedule text as caption (+ reply markup), instead of two separate messages. Falls back to two messages if caption exceeds Telegram's 1024-char limit. Also adds BatchMessageEditor helper that transparently handles EditMessageText vs EditMessageCaption depending on whether the batch message is a text or photo message. Updated all handlers and web service to use this helper. Version bump to 1.9.7.
