POST /purchase-rounds/{id}/announce renders the route's round_announced
MailTemplate with simple {{variable}} substitution (app/services/
mail_rendering.py) for every active participant on the route, sends
via Postal's real HTTP API (app/services/postal.py — request/response
shapes verified directly against docs.postalserver.io, not guessed),
and records one MailLog row per attempt (sent/failed, Postal's
message id + token for the future webhook in 7c, denormalized
rendered_subject so the log reflects what was actually sent even if
the template changes later). A failed send for one participant doesn't
abort the rest — each attempt is isolated and committed individually.
Route gained sender_name/sender_email in 7a; both are now populated
for the real route from the historical emails ("Finn Gram - Fælles
Vinindkøb <finn@vinindkoeb.dk>") directly in the DB, since there's no
Route CRUD API yet.
Verified end-to-end against the real Postal instance: a real test
email was sent and received via an isolated throwaway Organization/
Route/Participant/PurchaseRound/MailTemplate sandbox (never the real
route's 308 participants), MailLog captured the correct Postal message
id/token, and a temporarily-invalid API key produced a clean
sent:0/failed:1 result with Postal's actual error message stored,
not a 500. All test data removed afterward; real route/participant
data confirmed untouched.
