ref(quart): Drop send_default_pii support

[ericapisani]

The data_collection option now fully governs user info, query string, and header capture in the Quart integration; send_default_pii is no longer consulted. Consolidates and dedupes the corresponding tests around data_collection cases.

Fixes PY-2836
Fixes #7607
