Add eventToShortText shared formatter and formatEventDate helper

Replaces 4 duplicated event-to-text formatters across repos with a single
shared function. Handles all item types: number+unit, checkbox (null content
returns date), select (truncated labels), datasource-search (medication),
date, string, boolean, and object fallbacks. Adds formatEventDate() for
centralized date formatting. Includes 21 tests.
