Fix send modals: from email and preview rendering

fetchBasicMailConfig() was calling the wrong endpoint (company-config
instead of default config). Also, the response has no .data wrapper so
from_mail was never extracted. Fixed in all three send modals.

Estimate and payment preview blob construction now falls back to the
raw response when .data is undefined, matching the invoice modal.
