Fix Monday.com push: format column values by column type

The root cause was sending raw text to checkbox, status, dropdown, and
date columns. Monday.com requires specific JSON structures per type.

- Store column types in _columnTypes when Fetch Columns is clicked
- Format boolean/checkbox: {"checked": "true"/"false"}
- Format status/color: {"label": "value"}
- Format dropdown: {"labels": ["val1", "val2"]}
- Format date: parse MM/DD/YYYY to {"date": "YYYY-MM-DD"}
- Format email/phone/link with proper nested structures
- Text columns pass through as plain strings
