Add 113+ tests expanding coverage from 32% to 66% and fix 4 critical bugs

Added comprehensive test suite (244 total tests, all passing) covering mentor request/volunteer flows,
action handlers, and event utilities. Fixed high-severity bugs: missing error handling in _post_messages
causing KeyError crashes, validation incorrectly accepting empty skillsets, KeyError in SlackAPIError
handling, and incorrect state access in report dialog. Created reusable mock infrastructure for Slack/Airtable APIs.
