Guard customer_approved null/None in all templates

Some rows (schema drift, cancelled requests, manual status edits) have
customer_approved = NULL instead of the default 'none'. Templates called
.upper() on it blindly, causing a Jinja2 UndefinedError / 500 when the
customer player or admin pages loaded.

Replace all .upper() calls with (value or 'none').upper() and add truthy
checks before rendering the approved choice in status.html and
dashboard.html.
